Assure wayland output interface creation path

Browse source 
Summary:
The Wayland and XDG output interfaces are created or destroyed when the
output is en- or disabled. This follows a clear path of dependencies and
we should not check if this is indeed the case but instead assert on it.

Test Plan: Nested Wayland and Drm sessions.
