Moved SkCanvasVideoRenderer to media/filters.

SkCanvasVideoRenderer will be used for rendering YUV video streams by
the software compositor. To avoid circular dependencies cc/ cannot depend
on webkit/ hence the move.

Also changed the interface of SkCanvasVideoRenderer::Paint to accept
gfx::RectF instead of gfx::Rect. The gfx::Rect was converted to a
floating point SkRect anyway and we actually use the floating point
version from the software compositor.
