wayland: Fix input/opaque regions calculation on hidpi

Browse Source 
Commit 6a92c6f83 unintendedly broke input/opaque region calculations
on hidpi. Most visible side effect is that clicking is only allowed
in the upper-left quarter of windows.

The surface coordinates are returned in logical unscaled buffer
size. We're however interested in actor coordinates (thus real
pixels) here.

As it is a bit of a detour how the scale to be applied is calculated,
refactor a meta_wayland_actor_surface_get_geometry_scale() function
that we can use it here, and use it consistently for surface size and
the given regions.
