`util.getCallSite` returns an array of call site objects. Rename the
function to reflect that it returns a given count of frames captured
as an array of call site object.
Renames the first parameter `frames` to be `frameCount` to indicate
that it specifies the count of returned call sites.

Trim off irrelevant internal stack frames for require(esm) warnings

When a ESM module cannot be loaded by require due to the presence
of TLA, its module status would be stopped at kInstantiated. In
this case, when it's imported again, we should allow it to be
evaluated asynchronously, as it's also a common pattern for users
to retry with dynamic import when require fails.

As the documentation states, the `context.importAssertion` should be
still supported and emit a warning. This is true for the `load` hook,
but not correct for context of the `resolve` hook.
This commit fixes the inconsistency.

Previously we assumed if `--experimental-detect-module` is true, then
`--experimental-require-module` is true, which isn't the case, as
the two can be enabled/disabled separately. This patch fixes the
checks so `--no-experimental-require-module` is still effective when
`--experimental-detect-module` is enabled.
Drive-by: make the assertion messages more informative and remove
obsolete TODO about allowing TLA in entrypoints handled by
require(esm).

This previously compiles a script and run it in a new context
to avoid global pollution, which is more complex than necessary
and can be too slow for it to be reused in other cases. The
new implementation just checks the frames in C++ which is safe
from global pollution, faster and simpler.
The previous implementation also had a bug when the call site
is in a ESM, because ESM have URLs as their script names,
which don't start with '/' or '\' and will be skipped. The new
implementation removes the skipping to fix it for ESM.

When V8 creates a context for snapshot building, it does not
install Error.stackTraceLimit. As a result, error.stack would
be undefined in the snapshot builder script unless users
explicitly initialize Error.stackTraceLimit, which may be
surprising.
This patch initializes Error.stackTraceLimit based on the
value of --stack-trace-limit to prevent the surprise. If
users have modified Error.stackTraceLimit in the builder
script, the modified value would be restored during
deserialization. Otherwise, the fixed up limit would be
deleted since V8 expects to find it unset and re-initialize
it during snapshot deserialization.

This unflags --experimental-require-module so require(esm) can be
used without the flag. For now, when require() actually encounters
an ESM, it will still emit an experimental warning. To opt out
of the feature, --no-experimental-require-module can be used.
There are some tests specifically testing ERR_REQUIRE_ESM. Some
of them are repurposed to test --no-experimental-require-module.
Some of them are modified to just expect loading require(esm) to
work, when it's appropriate.

This patch implements a "module-sync" exports condition
for packages to supply a sycnrhonous ES module to the
Node.js module loader, no matter it's being required
or imported. This is similar to the "module" condition
that bundlers have been using to support `require(esm)`
in Node.js, and allows dual-package authors to opt into
ESM-first only newer versions of Node.js that supports
require(esm) while avoiding the dual-package hazard.
```json
{
"type": "module",
"exports": {
"node": {
// On new version of Node.js, both require() and import get
// the ESM version
"module-sync": "./index.js",
// On older version of Node.js, where "module" and
// require(esm) are not supported, use the transpiled CJS version
// to avoid dual-package hazard. Library authors can decide
// to drop support for older versions of Node.js when they think
// it's time.
"default": "./dist/index.cjs"
},
// On any other environment, use the ESM version.
"default": "./index.js"
}
}
```
We end up implementing a condition with a different name
instead of reusing "module", because existing code in the
ecosystem using the "module" condition sometimes also expect
the module resolution for these ESM files to work in CJS
style, which is supported by bundlers, but the native
Node.js loader has intentionally made ESM resolution
different from CJS resolution (e.g. forbidding `import
'./noext'` or `import './directory'`), so it would be
semver-major to implement a `"module"` condition
without implementing the forbidden ESM resolution rules.
For now, this just implments a new condition as semver-minor
so it can be backported to older LTS.

This implements an API for users to intentionally flush the
accumulated compile cache instead of waiting until process
shutdown. It may be useful for application that loads dependencies
first and then either reload itself in other instances, or spawning
other instances that load an overlapping set of its dependencies -
in this case its useful to flush the cache early instead of waiting
until the shutdown of itself.
Currently flushing is triggered by either process
shutdown or user requests. In the future we should simply start the
writes right after module loading on a separate thread, and this method
only blocks until all the pending writes (if any) on the other thread
are finished. In that case, the off-thread writes should finish long
before any attempt of flushing is made so the method would then only
incur a negligible overhead from thread synchronization.
