Original issue's description:
> Clean up WebMediaPlayerAndroid needs_establish_peer_
>
> needs_establish_peer_ has been used to skip actual estalishing a surface
> texture peer based on many conditions. Not all places that modify
> actually checks all these conditions so there are bound to be some bugs.
>
> This CL aims to tease out all these different conditions and put them in
> a single function EstablishSurfaceTexturePeerIfNeeded. This function
> should be called any time these conditions are changed. Makes for much
> saner reading.
