xwayland: Update root window size when desktop size changes

Browse Source 
This fixes grabs on InputOnly windows whose parent is the root window
failing with GrabNotViewable. This is due to window->borderSize/windowSize
being computed as clipped by its parent, resulting in a null region.

Setting up the right size on the root window makes the InputOnly size
correct too, so the GrabNotViewable paths aren't hit anymore.
