[clang] [CMake][HLSL] Add SPIRV to target list for build (PR #86323)

[Chris B via cfe-commits]

https://github.com/llvm-beanz created https://github.com/llvm/llvm-project/pull/86323

This change just enables the SPIR-V target by default in the HLSL build configurations. Since SPIR-V support is something we expect from the full HLSL compiler releases for pairity with DXC we should enable it in the default developer workflow.
