4fb9443d - [flang][OpenACC] Diagnose illegal routine calls in parallel loops (#190068)

[flang][OpenACC] Diagnose illegal routine calls in parallel loops (#190068) Add routine call checking to `AccStructureChecker` to reject OpenACC routine calls whose parallel level is incompatible with the enclosing loop directive (e.g., calling a worker‑level routine from a vector‑parallel loop), as required by the OpenACC specification.
