[M120 Migration][MM] Enable video hole when in full-screen mode in the public profile.

[M120 Migration][MM] Enable video hole when in full-screen mode in the public profile.

In accordance with the policy, video hole should only be enabled
when the video is in full-screen mode in the public profile.
Therefore, video hole should be dynamically turned on/off
based on whether the video is in full-screen mode or not.

- |esplusplayer_enable_video_hole| is used for this feature.
- Create MediaPlayerESPlusPlayerCommon because |esplusplayer_enable_video_hole|
can be used only for the public profile.
- Extract |SetBufferType| function that sets the buffer type
because the buffer type should be always 'copy' to use
|esplusplayer_enable_video_hole| in the public profile.
- Extract |PrepareVideoHole| function that calls video hole-related apis
to keep the following function call order.
esplusplayer_set_video_frame_buffer_type -> esplusplayer_set_display
-> esplusplayer_enable_video_hole -> esplusplayer_prepare_async
