Convert ReactHorizontalScrollView to Kotlin

Summary:
Convert `ReactHorizontalScrollView.java` to `ReactHorizontalScrollView.kt` using idiomatic Kotlin while preserving the public API surface.

Key changes:
- `ReactHorizontalScrollView.java` replaced by `ReactHorizontalScrollView.kt`
- `ReactHorizontalScrollViewManager.kt` updated to use Kotlin property access syntax for `scrollEnabled`, `stateWrapper`, and `fadingEdgeLengthStart/End`
- Static helper methods (`findDeepestScrollViewForMotionEvent`) moved into the companion object
- Public API surface preserved: only additive `synthetic` constructor from `JvmOverloads`

Changelog:
[Android][Changed] - Convert `ReactHorizontalScrollView` from Java to Kotlin
