Convert TextLayoutManager to Kotlin and Make Internal (#51966)

Summary: Pull Request resolved: #51966 This starts off mechanically, but needed a couple changes: 1. Some null handling changes to `TextTransform` internals 2. We type MapBuffer keys as `Int` instead of `Short`, because Kotlin does not allow the implicit widening cast that Java does. I also made these internal 3. Some shifts around casting 4. Mark TextLayoutManager internal, and remove usages of `UnstableReactNativeAPI` I verified that there were no usages of the Java side of TextLayoutManager throughout `react-native-libraries`, so marking TextLayoutManager internal is unlikely to break 3p libraries.
