[clang] [mlir] [MLIR][OpenMP] Add OpenMP_IntLikeTypeInterface to allow other dialect inputs to omp ops (PR #196363)

Why did you decide to opt for a new interface instead of just converting the CIR integers into mlir intrinsic integer types?

I'm worried that with this verifier change, you could have valid OpenMP dialect code using types which are not supported by the translation to LLVM-IR
