Add @DoNotStripAny to AnimationBackendChoreographer (#55465)

Summary:
Pull Request resolved: #55465

- AnimationBackendChoreographer.resume() and pause() are called from C++ via
  JNI reflection in JAnimationBackendChoreographer.cpp, but the class had no
  ProGuard/R8 protection annotation
- R8 renames the methods during minification, causing NoSuchMethodError at
  runtime when JNI looks up "resume" by name
- Every other JNI-accessed class in the fabric package (FabricUIManager,
  ComponentFactory, StateWrapperImpl, EventEmitterWrapper, EventBeatManager,
  MountItem) already uses DoNotStripAny — this was the only one missing
