backend/wayland: implement the output layer API

Browse source 
The output layer API is implemented using subsurfaces. I chose to
implement this API in the Wayland backend before doing so in the DRM
backend, because it's way easier on Wayland. On DRM, one needs to figure
out how buffers can be mapped to KMS planes (libliftoff can help) and
perform atomic test-only commits (our current DRM backend isn't ready
for this).
