output: Change wlr_output_add_software_cursors_to_render_pass to take buffer coordinates

Browse Source 
Since wlr_damage_ring now only works with buffer local coordinates, this
creates an inpedance mismatch for compositors that want to use this
function. Instead of compositors needing to the the conversion itself,
change thu function to take buffer local coordinates directly.
