[flang][OpenMP] Guard lastprivate scoping on DO (#157760)
Add HLFIR FileCheck ensuring `lastprivate(v)` on an `omp do` is realized
as privatization on the inner wsloop and not on the enclosing `omp
parallel`.
This matches OpenMP semantics and prevents regressions.

- No `private(v)` at `omp.parallel`
- `omp.wsloop ... private(...)` present

Unable to reproduce #157035 on current main; this test documents the
expected lowering.
