wlr-foreign-toplevel-management-v1: Simply leave and destroy code

Browse source 
We send the output_leave event and destroy a toplevel_output both if our
output_leave listener is called, or if the underlying wlr_output is
destroyed.

We somewhat clumsily reused the output_leave listener, which meant that
even though we had the toplevel output, we went out of our way to let
the output_leave handler find said toplevel_output again.

Simplify both pathways by adding a toplevel_output_leave function.
Should have no functional changes.
