HLSL texture intrinsic test first draft. (#3583)

* HLSL texture intrinsic test first draft.

* Some updated to texture-intrinsics.slang

* Update dx11 test config in texture-intrinsics.slang

* made some edits that shouldn't matter, but commiting once more to be sure

* Switch to filecheck-buffer and differing output values per api

* Forgot to uncomment one function and updated expected values.

* Delete tests/hlsl-intrinsic/texture/texture-intrinsics.slang.expected.txt

* Cubemap SampleGrad

* Enable Vulkan and have SampleCmpLevelZero ifdefed out for Vulkan
