Vlad Zahorodnii 4bfb0acc17 Make Workspace track managed outputs
This change adjusts the window management abstractions in kwin for the
drm backend providing more than just "desktop" outputs.

Besides that, it has other potential benefits - for example, the
Workspace could start managing allocation of the placeholder output by
itself, thus leading to some simplifications in the drm backend. Another
is that it lets us move wayland code from the drm backend.
