📺 Move PiP code upstream.

This moves Picture in Picture code into the public Chromium repository.
In addition it:
- Renames VideoPersisterInternal to PictureInPictureController.
- Makes PictureInPictureController not a singleton.
- Removes shouldDelayFullscreenModeChange.
- Uses the deprecated enterPictureInPicture zero argument method to
  avoid having to include the class of the argument, which may not yet
  be present on all builders. (Using the deprecated method is easier
  than loading the class via reflection.)

PIP: implement AppHooks' shouldDetectVideoFullscreen in Chromium.

This will allow us to remove the implementation downstream without
breaking the official builds. This change will also allow PIP to
actually work with a Chromium build.
