fix(text): support start and end text alignment (#57201)

Summary:
Closes https://github.com/react/react-native/issues/45255.

Adds `textAlign: 'start' | 'end'` support for Text and TextInput across the JS types, Android, iOS, and Fabric text conversion paths.

- Android legacy Text and TextInput now accept logical `start`/`end` alignment values.
- Fabric preserves `start`/`end` as distinct `TextAlignment` values and resolves them against layout direction for iOS paragraph layout.
- Existing `left`/`right` behavior is left unchanged to avoid changing current RTL semantics.

This replaces https://github.com/react/react-native/issues/57007 because the original fork became locked and could not be updated after the upstream conflict.

## Changelog:

[GENERAL] [ADDED] - Add support for `textAlign: 'start'` and `textAlign: 'end'`.

Pull Request resolved: https://github.com/react/react-native/pull/57201

Test Plan:
- `yarn build-types`
- `yarn test-typescript`
- `yarn flow-check`
- `./node_modules/.bin/prettier --check packages/react-native/Libraries/Components/TextInput/TextInput.d.ts packages/react-native/Libraries/Components/TextInput/TextInput.flow.js packages/react-native/Libraries/StyleSheet/StyleSheetTypes.d.ts packages/react-native/Libraries/StyleSheet/StyleSheetTypes.js packages/react-native/types/__typetests__/index.tsx packages/react-native/ReactNativeApi.d.ts`
- `./gradlew ktfmtCheck -Preact.internal.useHermesStable=true --no-daemon`
- `./gradlew :packages:react-native:ReactAndroid:testDebugUnitTest --tests com.facebook.react.views.textinput.ReactTextInputPropertyTest.testTextAlign --tests com.facebook.react.views.text.TextAttributePropsTest -Preact.internal.useHermesStable=true --no-daemon`
- `./gradlew ':packages:react-native:ReactAndroid:buildCMakeDebug[arm64-v8a][hermestooling,jsi,etc]' -Preact.internal.useHermesStable=true --no-daemon`
- `git diff --check`

The Android unit test and CMake checks were run from an ASCII-only temporary worktree because Kotlin unit test compilation in my main checkout fails before running these tests when the workspace path contains non-ASCII characters.
