Support HLSL SV_GroupThreadId attribute. For `directx` target, translate it into `dx.thread.id.in.group` in clang codeGen and lower `dx.thread.id.in.group` to `dx.op.threadIdInGroup` in LLVM DirectX backend. For `spir-v` target, translate it into `spv.thread.id.in.group` in clang codeGen and lower `spv.thread.id.in.group` to a `LocalInvocationId` builtin variable in LLVM SPIR-V backend. Fixes: #70122
