Subject: [PATCH] Move using declarations into AnimationBackend class (#54057)

Summary:

## Changelog:

[General] [Changed] - Move using declarations into AnimationBackend class

names like `facebook::react::Callback` is a bit too generic and it'll be included in the scope whenever AnimationBackend.h is included in; `StartOnRenderCallback` already exists in c++ native animated (there we also nest the `using`s under class)
