xdg-shell: Drop desktop environment specific state allocations

Instead of allocating state ranges that desktop environments can use as
they want, let them introduce their own protocol and their own enums.

If such desktop environment protocols need the configure/ack_configure
semantics, they can design their protocols to extend xdg_surface, and
make their private configure events a latched state tied to
xdg_surface.configure.
