Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50809
Configures `react-native/metro-babel-transformer` (used by `react-native/babel-preset`) to parse source using `hermes-parser` to target React 19. This changes components written with Component Syntax to stop generating `forwardRef` calls (because `ref` is now a prop).
Most of this was already accomplished in https://github.com/facebook/react-native/pull/50377 ({D72070021}), but this call site was missed.
Changelog:
[General][Changed] - Configured Hermes Parser to target React 19, resulting in Component Syntax no longer producing `forwardRef` calls.

Pull Request resolved: https://github.com/facebook/react-native/pull/39819
Bump `hermes-parser` packages to the latest released version.
Changelog: https://github.com/facebook/hermes/blob/main/tools/hermes-parser/js/CHANGELOG.md
Notable changes:
- Upgraded to the lastest version of emscripten for the parser.
- The babel interop logic now more closely matches babel's AST.
- The biggest change is we now add the `extra.raw` properties to literal nodes, which results in Babel more closely outputting literal sources. e.g. previously the following would happen `1.0` -> `1`, `'foo'` -> `"foo"` and `1n` -> `1` but now the raw source value is preserved.
- Upgraded `prettier-plugin-hermes-parser` to use the latest prettier formatting logic, which causes some minor formatting changes.
- `hermes-parser` no longer fails when the `component` name is used within a function type, e.g. `type Foo = (component: string) => void`.

Pull Request resolved: https://github.com/facebook/react-native/pull/38771
Changelog: [Internal]
Metro has been passing `inlineRequires: false` to Babel transformers for the last 5 years (D9636747), as the inline requires transform had been hoisted into the transform worker. Here we clean up the unused code paths in React Native's implementations of the Metro Babel transformer API, and the unused properties in the API itself.
