Summary:
Adds `ArrayBuffer` support to C++ TurboModules. This includes:
- Codegen support for `ArrayBufferTypeAnnotation` in module specs
- `AsyncArrayBuffer` — a move-only bridging type for holding ArrayBuffer data off the JS thread
- `Bridging<AsyncArrayBuffer>::toJs` for resolving promises with native-backed or owned-bytes buffers
iOS and Android support will follow in separate PRs. The new codegen type is currently restricted to C++ TurboModules via `excludedPlatforms: ['iOS', 'android']`.
## Changelog:
[GENERAL] [ADDED] - Add `ArrayBuffer` support to C++ TurboModules
Pull Request resolved: #56729
Test Plan:
- JS parser/generators tests added.
- New bridging unit tests in `BridgingTest.cpp` cover `AsyncArrayBuffer` construction and JS bridging.
- `rn-tester`: `getArrayBuffer`, `processAsyncBuffer`, and `getAsyncBuffer` methods added to `NativeCxxModuleExample` in demo app.
