layer_shell: order destroying before sway_output

Both sway_output and sway_layer_shell listen to wlr's output destroy event,
but sway_layer_shell needs to access into sway_output's data strucure and needs
to be destroyed first.

Resolve this by making sway_layer_shell listen to a new event that happens at
start of sway_output's destroy handler
