window: Only update the unconstrained rect when we actually moved/resized

Browse Source 
Since Wayland configures are more of a hint to the client than anything,
we don't want to save the unconstrained rect when we're just hinting to
the client that it should resize, since it could ignore us. This would
get us stuck in a loop, since meta_window_move_resize_now would use the
unconstrained_rect to resize, and we don't remove the resize from the
queue if we have an outstanding request like that.

This fixes a bunch of traffic / CPU usage when trying to resize
weston-terminal.
