xwayland: Don't send KeyRelease events on wl_keyboard::leave 

Commits 816015648f and
fee0827a9a made it so that
wl_keyboard::enter doesn't result in X clients getting KeyPress events
while still updating our internal xkb state to be in sync with the
host compositor.

wl_keyboard::leave needs to be handled in the same way as its
semantics from an X client POV should be the same as an X grab getting
triggered, i.e. X clients shouldn't get KeyRelease events for keys
that are still down at that point.

This patch uses LeaveNotify for these events on wl_keyboard::leave and
changes the current use of KeymapNotify to EnterNotify instead just to
keep some symmetry between both cases.

On ProcessDeviceEvent() we still need to deactivate X grabs if needed
for KeyReleases.
