Investigate loop inversion problem.

[kaizhangNV]

We noticed that some render engine renders artifacts image because of slang in D3D. After some initial investigation, we found out this is related to our loop inversion algorithm.

We make it an internal option for now and default off, we will re-enable it after figuring out the issue.

Lowering to P2. Will revisit once we get the capture/replay framework up.
