Update pointer and tablet focus when focused window is closed

Prior to dropping Deleted, we implicitly relied on the fact that the
QPointer storing the focused window will be reset to null when the
window is closed so we didn't include any cleanup logic.

After dropping Deleted and extending the lifetime of the original
window, it's no longer the case and we have to explicitly handle closing
the window otherwise kwin can encounter unexpected cases.
