compositor: drop wlr_surface.{sx,sy}

The concept of a persistent accumulated surface offset is wrong
from a protocol point-of-view. wl_surface.offset is tied to a
commit, its interpretation depends on the surface role.

For example, with the following sequence:

    wl_surface@1.offset(1, 1)
    wl_surface@1.commit()
    wl_pointer@2.set_cursor(wl_surface@1, 42, 42)

The final cursor hotspot is (42, 42): the commit which happened
before the set_cursor request has no impact on the hotspot
computation.

The wlr_output_cursor logic already uses wlr_surface.current.{dx,dy}.
wlr_scene's drag icon doesn't, update it accordingly.
