Move cc::VideoResourceUpdater to media.

This class is used by the media (and blink) code directly to produce
video resources for submission to the viz display compositor.
cc::VideoLayerImpl also uses it for this, but is deprecated and
eventually cc won't use this class at all. So we move it out of cc/ to
the media/ component.

Also satisfies a TODO and moves the SharedBitmapReporter from
viz/common/ to viz/client/ as it is a part of the client library,
and expand on the class comment to explain how to use it more.
