Make keyboard focus a pointer constraints necessity

Browse source 
Summary:
This patch changes KWin's pointer constraining behavior by only allowing
constraints if the surface has keyboard focus. In case the client activation
state changes, it rechecks it.

Test Plan:
Manually with the pointer constraints test application and opening the
launcher by pressing meta. Also amended autotest.
