backend/multi: emit destroy signal before destroying child backends

Some users might want to destroy the multi backend when a child
backend is being destroyed. However, they can't destroy the multi
backend if it's already in the process of being destroyed.

The destroy signal was changed to be emitted after destroying child
backends in babdd6ccf757 ("backend: fix use-after-free when destroying
backends"). However, this was done to accomodate for an old
"output_remove" event on backends, which has long been dropped in
favor of wlr_output.events.destroy.

This patch follows the same principle as 5d639394f3e8
("types/output: emit destroy event before destroying global").
