Make sure BitmapUploader Returns Resources

bitmap_uploader was inheriting from mus::mojom::SurfaceClient directly
instead of from WindowSurfaceClient. Unfortunately, ReturnResources
callbacks were going to the mus client lib and not to BitmapUploader and so
BitmapUploader never returned any resources.

This CL makes BitmapUploader a mus::WindowSurfaceClient and sets itself
as the client for the provided WindowSurface.
