This change pulls some code from the DirectX backend into a new LLVMFrontendHLSL library to share utility data structures between the HLSL code generation in Clang and the backend in LLVM. This is a small refactoring as a first start to get code into the right structure and get the library built and dependencies correct. Fixes #58000 (https://github.com/llvm/llvm-project/issues/58000) Reviewed By: python3kgae Differential Revision: https://reviews.llvm.org/D135110
