Remove enum movement_direction

There's no point having both movement_direction and wlr_direction. This
replaces the former with the latter.

As movement_direction also contained MOVE_PARENT and MOVE_CHILD items,
these are now checked specifically in the focus command and handled in
separate functions, just like the other focus variants.
