window/x11: Add flag to thaw commits after resize

Browse Source 
To be able to thaw commits following a resize that might have frozen
commits, to keep freezes and thaws even, we need a way to tell whether
a repaint should also thaw commits.

Add a flag to `MetaWindowX11` and the appropriate functions to set and
query it.
