Remove deprecated constructors for TextInput *Event classes (#52535)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52535

Those constructors are no longer necessary. They're deprecated + the class is internal so they're not breaking changes.
I'm just cleaning them up as they're not needed anymore.
