  [CodeGen] @llvm.experimental.stackmap make operands immediate (#117932)

This pull request modifies the behavior of the
`@llvm.experimental.stackmap` intrinsic to require that its two first
operands (`id` and `numShadowBytes`) be **immediate values**. This
change ensures that variables cannot be passed as two first arguments to
this intrinsic.

### Testing
- Added new test cases to ensure errors are emitted for non-immediate
operands.
- Ran the full LLVM test suite to verify no regressions were introduced.
