- Improves MMNV request handling by tracking active clock requests per session and returning the effective requested rate for each module.
- Treats sentinel clock requests (`0` / negative values) as request clears.
- Preserves VP9 segment maps across inter frames, resetting them for key/intra/size-change cases.
- Avoids stale VP9 motion-vector state by disabling previous MV lookup on key frames and clearing output MVs for intra-only frames.
This fixes VP9 playback corruption seen in several Just Dance videos where stale segmentation/MV state could leak across frames and produce blocky/discolored output until a later refresh frame.
The MMNV changes also make the service behavior closer to what games expect when requesting and clearing NvDec clocks, removing the stub spam for this service.
