Reviewed by Simon Fraser.

In order to draw iframes the right size, we get the layer size from the parent
process and send it to the iframe process in a DrawingArea::UpdateGeometry message.

In order to send the DrawingArea::DisplayDidRefresh message to the right process
as a result of a RemoteLayerTreeDrawingAreaProxy::CommitLayerTree message,
instead of calling didRefreshDisplay which does several things that don't relate
to subframe processes, just send the DrawingArea::DisplayDidRefresh which is the
only part we need for drawing to continue.
