wayland/pointer-constraints: Maybe constrain on pointer focus change

Browse Source 
Since Xwayland surface constraints might need to enable not only
because the constrained window appears focused, add a pointer focus
listener and try constrain whenever the pointer focus changes. It's
still required that a Xwayland window is focused to activate.
