Ozone Tests need fixing too i.e. MockDrmDevice etc

Thanks for reminder, Kalyan, but how about creating another new CL for that soon
after this CL to avoid this CL is getting too too large. Do you agree with this?

Fixing tests must be done here not in a followup. Patches that break tests are
reverted.
