Subject: [PATCH] layers.c: allow layer surfaces on disabled outputs

4f8b80700ea43546ffe116157820425009d04ccf added a check for the output
being enabled when creating a layershell surface with automatic output
selection. This causes labwc to send a `layer_surface.close()` and
`wl_surface.destroy()` to layershell clients when creating a new
layershell surface on a disabled output which is still part of the layout
(e.g. `wlopm --off`).

This MR replaces the `output_is_usable()` check with a dedicated check,
bypassing the check for the output being enabled.

Fixes: #3410
