[dxvk] Improve handling of cpu-frametime related stutters for low-latency frame pacing
...
Stutters less this way because we increase the sensitivity to mark frames as outliers, so that they don't get used for predicting the next frame. The actual "optimal" threshold is still to be fine-tuned, but this one worked really well.

[dxvk] Optimize flush heuristic for low-latency

Possibly can be optimized more, but just changing these numbers already had a huge effect, especially for games having a small number of submissions to begin with.

[dxvk] Improve robustness of frame pacer initialization
...
In d3d9 there were situations where the first frameId was 22, although in d3d11 it always started at 17. This did cause issues especially when waiting for fences which didn't get signaled for these frameIds.

[dxvk] Optimize GPU start measurement for low-latency frame pacing
...
In practice, this change affects oversubscribed threading situations where waking up the "dxvk-queue" thread potentially can cause delays in the 100s of microseconds. For a lot of situations this change isn't affecting measurements in a meaningful way. Possibly affects AMD where vkQueueSubmit execution time is non-zero.
