input/keyboard: wlr_keyboard_group enter and leave

This adds support for wlr_keyboard_group's enter and leave events. The
enter event just updates the keyboard's state. The leave event updates
the keyboard's state and if the surface was notified of a press event
for any of the keycodes, it is refocused so that it can pick up the
current keyboard state without triggering any keybinds.
