  [HLSL][SPIR-V] Add SV_DispatchThreadID semantic support (#82536)

Add SPIR-V backend support for the HLSL SV_DispatchThreadID semantic
attribute, which is lowered to a @llvm.dx.thread.id intrinsic in LLVM
IR. In the SPIR-V backend, this is now correctly translated to a
`GlobalInvocationId` builtin variable.

Fixes #82534
