refactor(core): cleanup feature flags for js source inclusion (#19463)
Remove `ExtensionFileSourceCode::LoadedFromFsDuringSnapshot` and feature
`include_js_for_snapshotting` since they leak paths that are only
applicable in this repo to embedders. Replace with feature
`exclude_js_sources`. Additionally the feature
`force_include_js_sources` allows negating it, if both features are set.
We need both of these because features are additive and there must be a
way of force including sources for snapshot creation while still having
the `exclude_js_sources` feature. `force_include_js_sources` is only set
for build deps, so sources are still excluded from the final binary.

You can also specify `force_include_js_sources` on any extension to
override the above features for that extension. Towards #19398.

But there was still the snapshot-from-snapshot situation where code
could be executed twice, I addressed that by making `mod_evaluate()` and
scripts like `core/01_core.js` behave idempotently. This allowed
unifying `ext::init_ops()` and `ext::init_ops_and_esm()` into
`ext::init()`.

This directory contains the typescript compiler and a small compiler host for the runtime snapshot.

How to upgrade TypeScript.

The files in this directory are mostly from the TypeScript repository. We currently (unfortunately) have a rather manual process for upgrading TypeScript. It works like this currently:

  1. Checkout denoland/TypeScript repo in a separate directory.
  2. Add Microsoft/TypeScript as a remote and fetch its latest tags
  3. Checkout a new branch based on this tag.
  4. Cherry pick the custom commit we made in a previous release to the new one.
  5. This commit has a "deno.ts" file in it. Read the instructions in it.
  6. Copy typescript.js into Deno repo.
  7. Copy d.ts files into dts directory.
  8. Review the copied files, removing and reverting what's necessary

So that might look something like this:

git clone https://github.com/denoland/TypeScript.git
cd typescript
git remote add upstream https://github.com/Microsoft/TypeScript
git fetch upstream
git checkout v3.9.7
git checkout -b branch_v3.9.7
git cherry pick <previous-release-branch-commit-we-did>
npm install
gulp local
rsync built/local/typescript.js ~/src/deno/cli/tsc/00_typescript.js
rsync --exclude=protocol.d.ts --exclude=tsserverlibrary.d.ts --exclude=typescriptServices.d.ts built/local/*.d.ts ~/src/deno/cli/tsc/dts/
