[HLSL] Make ray queries safer.

[Vecvec]

Connections
DirectX side of #6761
Does similar things to #8390 but for hlsl instead

Description
Passes a tracker around with the ray query to track its initialization status. This does similar things to the spir-v back-end with these notable exceptions:

1. Most functions are inline.
   • I was unsure how inouts behave with ray queries, and writing inline is much easier in HLSL. Most of the functions are fairly small, and aren't used very frequently.
2. No tmax tracker.
   • Unlike spir-v, CommittedRayT is defined in HLSL when if there hasn't been a committed hit (Note: there is a bug in dxc when outputting spir-v though, see [SPIR-V] Conversion from CommittedRayT to OpRayQueryGetIntersectionTKHR can introduce UB microsoft/DirectXShaderCompiler#7860, but I don't think that the intent for the HLSL backend is to compile into spirv)

Testing
Same tests as #8390
