This property lets the driver specify which format+modifier combinations are actually supported with tearing, and we use that in the dmabuf feedback to make tearing work in more cases (with sync fallback) - matching the approach taken in KWin.

Are there kernel patches necessary for this to work? I tried a few games (Hades II, Portal 2) on my MSI Claw and none seem to tear, even with this PR. The same in-game settings on AMD do tear.
