Remove unnecessary classes inside com.facebook.react.uimanager.layoutanimation (#54730)

Summary:
Pull Request resolved: #54730

I'm deleting those 2 classes related to layout animation. They were needed only for legacy arch.
They're not needed anymore so they can go now.
Marked as breaking because those 2 classes were public, but I wasn't able to find meaningful usages in OSS

Changelog:
[Android] [Breaking] - Remove unnecessary classes inside `com.facebook.react.uimanager.layoutanimation` used in legacy architecture
