feat(android): make buffering strategy dynamic (#3756)

* chore: rework bufferConfig to make it more generic and reduce ReactExoplayerView code size
* feat: expose bufferingStrategy to app and change default behavior
rename disableBuffering undocumented prop to bufferingStrategy and document it.
before this change, default was 'dependingOnMemory'. It can trigger some unnecessary gc() call on android.

 Please note that the Android cache is a global cache that is shared among all components; individual components can still opt out of caching behavior by setting cacheSizeMB to 0, but multiple components with a positive cacheSizeMB will be sharing the same one, and the cache size will always be the first value set; it will not change during the app's lifecycle.
