layer shell: add wlr_layer_surface_v1_popup_surface_at()

Browse source 
This function will allow compositors to implement input handling in a
way consistent with rendering more easily.

Calling wlr_layer_surface_v1_surface_at() and checking if the result is
a wlr_xdg_popup is flawed as there may be subsurfaces in the popup tree.
