ci/windows,microsoft/spirv_to_dxil: Adding validation tests to spirv_to_dxil
These tests are based on Tint's SPIR-V reader unit tests. https://github.com/dneto0/spirv-samples/
We downloaded the SPIR-V files, assemble them with SPIRV-tools, and run them through spriv2dxil
with DXIL validation enabled.
Currently only 59 of 1111 tests are failing.
