  Fix metadirective loop variant safety checks

Classify candidate and fallback association from raw directive IDs so clauses are only converted for the selected variant.

Recognize data environments selected by enclosing metadirectives from the emitted OpenMP operation ancestry. Add regressions for unselected clauses and nested selected parallel regions.

Assisted with codex.
