Enable Android SurfaceView fullscreen video with WMPI
This CL enables SurfaceView fullscreen video with the unified media pipeline
in cases where we use the AVDA deferred rendering strategy today.
* There's a new media interface called SurfaceManager with two methods:
CreateFullscreenSurface() and NaturalSizeChanged().
* SurfaceManager is implemented by RendererSurfaceViewManager, which is a
RenderFrameObserver, and BrowserSurfaceViewManager, which is created for
each RenderFrame by MediaWebContentsObserverAndroid.
* BrowserSurfaceViewManager creates a ContentVideoView in response to a
CreateFullscreenSurface message, and registers it in a surface map that the
decoder can look up in the GPU process.
* WMPI interacts with SurfaceManager on behalf of the decoder. It passes
GpuVideoDecoder a callback for requesting surfaces which it calls before
initializing VDAs.
* In response to the callback, if the player is in fullscreen WMPI will pass
the request to the SurfaceManager which will return the surface id to GVD. If
the player is not in fullscreen WMPI will return a null surface id.
* When GVD gets a surface id back it completes its initialization by calling
VDA::Initialize with the surface id and the VDA will render to the given
surface.
* WMPI records that it got a surface request callback so that it knows that
future fullscreen transitions will require a restart of the decoder in order
to switch surfaces.
* A future CL will allow us to switch the surface dynamically without
requiring a restart.
