Revert 123227 - Extract first version of a RenderWidgetHost interface.

This begins the process of extracting RWH and RVH interfaces and
leaving RenderWidgetHostImpl and RenderViewImpl classes in content.
There will be parallel inheritance hierarchies, i.e. RWHImpl inherits
from RWH, RVH inherits from RWH, RVHImpl inherits from RVH and
RWHImpl.  Thus, chrome will only see the interfaces.

I fully expect that some of the things chrome needs from the RVH
interface, once I introduce that, will more properly belong on the RWH
interface, in which case I expect to move them there.  But first to
define the base interfaces.
