Source/Platform:

Adds a compositor layer type for video, WebVideoLayer, and a WebVideoProvider interface.

Source/WebCore:

Converts VideoLayerChromium / CCVideoLayerImpl to use a Platform WebVideoFrameProvider interface instead of a
WebCore VideoFrameProvider.

* WebCore.gypi:
* platform/graphics/chromium/VideoLayerChromium.cpp:
(WebCore::VideoLayerChromium::create):

Source/WebKit/chromium:

Adds implementation of WebVideoLayer and ports WebMediaPlayerClientImpl over to using it.
WebMediaPlayerClientImpl still exposes a WebCore::VideoLayerChromium* to the compositor via the platformLayer()
interface, but this is temporary until we can change the PlatformLayer typedef over to WebLayer.
