Summary:
- Current implementation does not follow CSS spec for rectangle boxes with corner angles. It is using non spec compliant algorithm to calculate start and end points. This PR follows the spec compliant algorithm to implement and makes sure Web, iOS and Android gradients are identical with corner angles.
- Also, currently it is using `CAGradientLayer` which does not support spec compliant start and end points i.e. start and end point can be outside of rectangle bounds. This leads to inconsistent gradients on iOS for corner angles compared to web and android. So this PR replaces it with `CGGradient`.
- I have also moved some files to make it easier to add more background image types in future.
## Changelog:
[GENERAL] [FIXED] - Linear gradient start and end point algorithm.

Test Plan:
- Added multiple gradient example which should be identical in all platforms (Web, iOS and Android) and tested thoroughly on all platforms. I think some visual test cases can help here.
- I have referred to [blink's](https://github.com/chromium/chromium/blob/main/third_party/blink/renderer/core/css/css_gradient_value.cc) implementation.
## Aside
Took a while to understand the [spec](https://www.w3.org/TR/css-images-3/#corner-gradient-example), but felt great after getting it. Gradients should be 100% identical on all platforms now. Sorry i missed testing cornered angles + rectangles earlier and I found out it is inconsistent on platforms just this weekend 😅

```typescript

obj: Readonly<{ str: string }>

}
export default codegenNativeComponent<NativeProps>('SomeComponent');
```
In this case the generated `EventEmitters.cpp` code would contain:
```c
obj.setProperty(runtime, "str", payloadArrayValue,obj.str);
```
while
```c
obj.setProperty(runtime, "str", payloadArrayValue.obj.str);
```
is expected.

We may see an NSRangeException when setting new AttributedString content, where setting the AttributedString itself changes selection (before we mutate it later).
It seems like the selection here is not in a good state yet in regards to the AttributedString backing exposed (since we are reading it while modifying it). So let's fold the logic for updating typing attributes into the collection of ignored work from non-user-selection updates, since programatically setting an AttributedString will already trigger updating typing attributes.
I also added a nil check here, which is unrelated to the crash, but it seems like we should have it for safety...

When breaking the last dependency, we created the `RCTApDependencyProvider` in the Codegen pod.
This is not an issue per sè. The problem comes in with the new template in Swift: ReactCodegen contains some headers with some C++ code that Swift can't really process.
That's why most libraries started failing in jobs like [this one](https://github.com/facebook/react-native/actions/runs/11906196751/job/33177904733): the template app was not able to load the `ReactCodegen` pod in the Swift app delegate.
Given that the app delegate only have to actually load the RCTAppDependencyProvider, I extracted that class in its own pod: ReactAppDependencyProvider.
The name of the pod does not follow the React-RCTXXX structure because that will create issues with the import statements and the `use_frameworks!` use case.
> [!NOTE]
> We need to update the template and change the `import ReactCodegen` to `import ReactAppDependencyProvider`

Currently, we assume any URL with a hostname of `10.0.2.2` or `10.0.3.2` (device-relative) is eligible for rewriting to `localhost` (frontend-relative), because we assume the device is an Android emulator. We rewrite these URLs between device and dev machine so that the rewritten URLs are reachable from the dev machine.
This diff narrows this logic so that we'll only rewrite URLs where the hostname matches the pre-existing list *and* this matches the host the device is actually connected on, according to its headers from the original connection.
The main motivation for this change is to unblock removing assumptions about device-reachable vs server-reachable hosts. Later in the stack we'll drop the hardcoded listing of `10.0.2.2` etc in favour of identifying URLs that target the dev server, from whatever network.
There's also an edge case fix here that `10.0.2.2` etc might actually refer to a remote LAN server, and not be an Android emulator's alias for for an emulator host.

This updates `open`, `close`, `read`, `write`, and `pipe` call sites to use
`folly::fileops` qualified name lookup.
This is the 2nd phase in a 3-phase change to remove folly's global definitions
of the posix functions that conflict with windows CRT.
The 1st phase created namespaces for folly's posix functions. The 2nd phase
updates callsites to use the qualified name of folly's `open`, `close`,
`read`, `write`, and `pipe` functions. The 3rd and final phase will remove
folly's globally defined posix functions and have windows CRT define them
again.
**What is the reason for this change?**
Folly's global definitions of posix functions on Windows causes `#include`
order issues if folly is not included first.
For example, when `gtest/gtest.h` is included before folly, gtest includes
`windows.h` and that declares `open`, `read`, and `chdir`, which creates
ambiguous references to folly's `open`, `read`, and `chdir`.
Another example is where posix functions go undeclared when
`folly/portability/windows.h` is included without other portability headers
(e.g., `folly/portability/unistd.h`). `folly/portability/windows.h` includes
`windows.h` in a way that only underscore versions of the posix functions are
available (e.g., `_open`, `_close`).
These issues create friction for windows development.
**Background: What is the purpose of `folly::portability::{fcntl,stdlib,sysstat,unistd}`?**
It is a portability layer to make posix functions available and behave
consistently across platforms. Some posix functions don't exist on windows
(e.g., `sysconf`). Some other posix functions, folly changes to adapt behavior
across platforms. For example, on windows folly defines `open`, `read`,
`write`, and `close` functions to work with sockets. Folly makes these
functions available in the global scope for convenience.

The extra space is now extending past the flex start edge vs flex end. RTL is the opposite. NickGerleman had deviated from the spec back in the day to match Chrome and it seems they made the adjustment recently. T208209388 is tracking the followup to align with the spec again. Basically, there is a notion of fallback alignment when certain justification/alignment values cannot actually apply. Right now we are falling back to flex start in all cases but we should fallback to start sometimes.

Its not optimal to reconstruct CompositeBackgroundDrawable everytime we add a layer to it.
With this change I'm adding an optimization to modify the underlying `LayerDrawable` in place instead of reconstructing everything. `LayerDrawable` has a pretty constrained API and some weirdish behaviors.
- `addLayer` - This API doesnt set the callback for the recently added layer so after adding the layer we also need to manually set the callback
- Mutating `LayerDrawable` in-place is not straightforward, I had to add a function that will figure out where each layer should be inserted
- `LayerDrawable` doesn't allow deleting an element which means that for this case in particular we do need to re-create `CompositeBackgroundDrawable`
- Newer Android versions allow `null` on `LayerDrawable` layers, but older versions do not, this implementation is mostly done this way to accommodate older versions. But also, even though newer versions can have `null` set on a layer `LayerDrawable` still doesn't handle it well and we get some bugs when removing and inserting a layer which the current implementation handles by not relying on null
This is all feature flagged. since it will only be enabled with the new drawables

When investigating [#47476](https://github.com/facebook/react-native/issues/47476), I found that the `secureTextInput` prop was not changing in the Mounting layer when changing it in JS.
I track down the problem to the `UIManager::cloneNode` method.
When we clone the node, we first merge the patch that arrives from React into the props controlled by setNativeProps, ignoring the patch's props that are controlled by React.
But then, we forgot to merge back the React's controlled property into the final props, effectively losing them.
This change adds an extra merging step, merging the props controlled with setNativeProps back into the patch of props controlled by React, and then using this new set of props as source of truth.

1948076b81/packages/react-native/sdks/hermes-engine/hermes-utils.rb (L227)
In a clean checkout however, this results in an error when archiving the Hermes directory due to the missing parent directory of the archive's destination.
This PR suggests adding a check for and optional creation of the existence of the archive directory before usage.
An alternative that I considered was ensuring the existence inside of the `artifacts_dir` function:
1948076b81/packages/react-native/sdks/hermes-engine/hermes-utils.rb (L198-L200)
But there's only one other call site, which already does the `mkdir -p`.

Now that we have `babel-plugin-syntax-hermes-parser` in `react-native/babel-preset` (since D63535216), it's no longer necessary to use `hermes-parser` directly in Metro in order to use newer Flow syntax.
Babel with `babel-plugin-syntax-hermes-parser` is generally preferable, because it intelligently falls back to parsing with Babel for any non-`flow` files.
See https://github.com/facebook/hermes/issues/1549 for context.
Changelog:
[General][Fixed] metro-config: Don't use `hermes-parser` by default, prefer `babel-plugin-syntax-hermes-parser`, which supports other syntax plugins.
