Classic confinement request: wayland-debug

I’m snapping my debug tool It needs to execute GDB with itself as a plugin, which then needs to run whatever application the user is trying to debug. I’m not yet sure if it makes sense to ship a copy of GDB with the snap, but either way the snap will need classic confinement in order to debug programs not inside the snap.

Require for classic understood so I vetted the publisher. Granting use of classic. This is now live.
