Summary:
On client side the newer wl_keyboard_release is used which is a
destructor call. On server side the shared destroy callback is used
and it's ensured that KWayland doesn't crash if called into the
KeyboardInterface between unbound and destroyed.
Test Plan:
Test case extended to cover the condition of an unbound
KeyboardInterface.

If the focused pointer and keyboard surface is the same we use pointer
clicks as a hint to which child surface should have keyboard focus.
Keyboard focus handling for sub surfaces is rather limited overall.
We just don't have a good model on how to determine which child surface
should get the keyboard focus. When passing focus to a surface there
is no way to know which of the sub-surfaces should get the focus.
Ideally the client should handle this, but that's just not the case.
The best we have is a reference through the pointer. But that's of
course also limited. Keyboard focus passed to the surface for another
reason (Alt+Tab) cannot select the proper sub-surface without interaction
from another input device.
