MetaWaylandPointerConstraint: Fix effective region calculation

Browse Source 
The when surface->input_region is NULL, it should be interpreted as the
whole surface region. If not, the effective input region is the
intersection of the buffer region and the input region set by
wl_surface.set_input_region. Add
meta_wayland_surface_calculate_input_region() that does this
calculation.
