Handle keyboard events during move/resize

When moving/resizing a window we don't want the keyboard events being
passed to the Clients. Instead we want to do the normal processing.

Unfortunately moving the window through the keyboard relies on warping
the pointer which is not (yet) available on Wayland. This means that this
is not yet working, but ending through enter/escape etc. is working as
expected.
