feat: implement enterPictureInPictureOnLeave prop for both platform (Android, iOS) (#3385)

* docs: enable Android PIP

* chore: change comments

* feat(android): implement Android PictureInPicture

* refactor: minor refactor code and apply lint

* fix: rewrite pip action intent code for Android14

* fix: add manifest value checker for prevent crash

* docs: add pictureInPicture prop's Android guide

* fix: sync controller visibility

* refactor: refining variable name

* fix: check multi window mode when host pause

- some OS version call onPause on multi-window mode

* fix: handling when onStop is called while in multi-window mode

* refactor:  enhance PIP util codes

* fix: fix FullscreenPlayerView constructor

* refactor: add enterPictureInPictureOnLeave prop and pip methods

- remove pictureInPicture boolean prop
- add enterPictureInPictureOnLeave boolean prop
- add enterPictureInPicture method
- add exitPictureInPicture method

* fix: fix lint error

* fix: prevent audio play in background without playInBackground prop

* fix: fix onDetachedFromWindow

* docs: update docs for pip

* fix(android): sync pip controller with external controller state

- for media session

* fix(ios): fix pip active fn variable reference

* refactor(ios): refactor code

* refactor(android): refactor codes

* fix(android): fix lint error

* refactor(android): refactor android pip logics

* fix(android): fix flickering issue when stop picture in picture

* fix(android): fix import

* fix(android): fix picture in picture with fullscreen mode

* fix(android): fix syntax

* chore(android): fix lint error

* fix(ios): fix enter background handler

* refactor(ios): remove redundant code

* fix(ios): fix applicationDidEnterBackground for PIP

* fix(android): fix onPictureInPictureStatusChanged

* fix(ios): fix RCTPictureInPicture

* refactor(android): Ignore exception for some device ignore pip checker

- some device ignore PIP availability check, so we need to handle exception to prevent crash

* fix(android): add hideWithoutPlayer fn into Kotlin ver

* refactor(android): remove redundant code

* fix(android): fix pip ratio to be calculated with correct ratio value

* fix(android): fix crash issue when unmounting in PIP mode

* fix(android): fix lint error

* Update android/src/main/java/com/brentvatne/react/VideoManagerModule.kt
