window: Don't use button grab modifiers with inhibit shortcuts

Browse Source 
On Wayland, if a client issues a inhibit-shortcut request, the Wayland
compositor will disable its own shortcuts.

We should also disable the default handler for the button grab modifier
so that button events with the window grab modifiers pressed are not
caught by the compositor but are forwarded to the client surface.

That also fixes the same issue with Xwayland applications issuing grabs,
as those end up being emulated like shortcut inhibition.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/642
