RN: Default Hermes Parser to reactRuntimeTarget: "19" (#52625)

Summary:
Pull Request resolved: #52625

Changes `react-native/babel-preset` so that by default, `hermes-parser` is configured with `reactRuntimeTarget: "19"`. This changes the compiled output of Component Syntax to not use `forwardRef` when a `ref` prop is present.

Additionally, this adds a new preset option property, `hermesParserOptions`. This object allows users of `react-native/babel-preset` to supply overrides for any `hermes-parser` options.

Changelog:
[General][Changed] - Configures `react-native/babel-preset` to target React 19 by default, meaning Component Syntax will not compile to `forwardRef` calls when a `ref` prop is present.
[General][Added] - Added support to `react-native/babel-preset` for a `hermesParserOptions` option, that expects an object that enables overriding `hermes-parser` options.
