Change surface layout in native and don't implement OnNewVideoLayoutListener
(therefore, the "android-display" module won't work).

When OpenGL ES2 is used (for software decoding, or when we need to do a
transformation like 360 videos), OnNewVideoLayoutListener won't be triggered
and mVideoWidth/Height will be 0. In that case, we should change the surface
layout using the MediaPlayer API.
