backend/wayland: give wlr_pointer ownership to wlr_wl_seat

Browse source 
All the code logic related to the pointer has been moved to its own file.

The seat is responsible for the lifetime of its wlr_wl_pointer(s), and assigning
them to the relevant wlr_wl_output. The wlr_wl_pointer becomes a simple helper
to manager the wlr_pointer associated to the seat's wl_pointer and its lifetime.
