Reland "Enable Windows NV12 overlays on waterfall"

This is a reland of 2be1f912

In addition to the original change, also temporarily mark video pixel
tests on the Intel HD630 bot as failing, and increment the test version
numbers for rebaselining. A follow-up CL will re-enable the tests.

Original change's description:
> Enable Windows NV12 overlays on waterfall
>
> We plan on shipping this via a finch experiment to Canary/Dev soon, and then
> enable it by default if we don't encounter major issues. This should only affect
> the DirectComposition pixel tests since we force-enable overlays for those
> tests. Other tests don't exercise DirectComposition code because those code
> paths are disabled unless the hardware supports it.
