Fix DS and VRR automation

[UjinT34]

Describe your PR, what does it fix/add?

Fix DS automation conditions. Fixes #9331
Fix VRR auto activation. Might fix #9230
Add misc:vrr = 3 to auto enable VRR for game or video content types. Can be used instead of a window rule #7621

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

There is no need to commit VRR state and deal with explicit sync inside ensureVRR. Next rendered frame should pickup new desired state. Legacy renderer is untested.
Needs more testing with vrr = 2 or vrr = 3 and monitors without VRR support.

Is it ready for merging, or does it need work?

Ready

might wanna drop DS changes

Isn't this all supposed to be gated behind the window being solitary anyways? DS requires a solitary window on the monitor and I assume so should vrr. PMONITOR->solitaryClient

direct_scanout = 1 works this way.
direct_scanout = 2 also checks for a fullscreen window with game content type to avoid DS activation for apps that don't work well with DS.
