wayland-keyboard: Notify clients of pending modifier state changes

Browse Source 
If we get a key event but still have pending modifier state changes we
need to send a modifiers event right away so that the key event can be
interpreted by clients correctly modified.

This case could happen when mutter/gnome-shell itself consumes the
modifier key press event such as with the overview key which by
default is triggered on super press.
