Add a new mode matching flag DRM_MODE_MATCH_TIMINGS_VRR. This is identical to DRM_MODE_MATCH_TIMINGS, except it requires the vsync pulse to remain anchored to the end of vtotal, as opposed to the start of the frame. VRR capable hardware can therefore treat matching modes as just variants of the same mode with a different vblank lengths.
