Fix origin for VideoResourceUpdater::CopyHardwarePlane

Historically it was using origin from the source shared image, while it
sends a copy to the display compositor. Destination for copy is created
using top left and CopySharedImage call will perform flip during it.

This CL fixes to use destination origin.

This CL is no-op, because the only case when we need frames to be
copied is hardware decoded frames and they are always top-left [1].
Frames that are created from webgl are already accessible cross-thread
and don't need the copy.
