Block geometry updates on move resize finish and don't configure xdg shell surfaces while blocked

Summary:
We send out too many configure requests when finishing move resize which
also triggers quick tiling. This change addresses the problem of the too
many configure requests by making the configure method check whether
geometry updates are blocked. And to make this work properly for the end
of finish move resize the complete method is wrapped in a geometry
update blocker.

BUG: 388072
FIXED-IN: 5.12.1

Test Plan:
Quick tiling test passes, both Wayland and X11 windows are
quick tiled correctly.
