[OMM] Add AllocateRayQuery2 DXIL Op

[bob80905]

Is your feature request related to a problem? Please describe.
According to the spec here:
https://github.com/microsoft/hlsl-specs/blob/main/proposals/0024-opacity-micromaps.md
There is a new DXIL Op that needs to be added as part of the OMM feature. AllocateRayQuery2 is a variant of the allocate ray query DXIL Op, but it accepts a new argument, as part of the new optional template argument that may be provided to RayQuery objects upon construction in HLSL.
We need a new DXIL Op, but it doesn't exist yet.

Describe the solution you'd like
Create AllocateRayQuery2, and run tests on DXIL files containing it. Test validation errors too.

Note this issue doesn't include HLK testing
