4c6a38c3 - [acc] Expand OpenACCSupport to provide getRecipeName and emitNYI (#165628)

[acc] Expand OpenACCSupport to provide getRecipeName and emitNYI (#165628) Extends OpenACCSupport utilities to include recipe name generation and error reporting for unsupported features, providing foundation for variable privatization handling. Changes: - Add RecipeKind enum (private, firstprivate, reduction) for APIs that request a specific kind of recipe - Add getRecipeName() API to OpenACCSupport and OpenACCUtils that generates recipe names from types (e.g., "privatization_memref_5x10xf32_") - Add emitNYI() API to OpenACCSupport for graceful handling of not-yet-implemented cases - Generalize MemRefPointerLikeModel template to support UnrankedMemRefType - Add unit tests and integration tests for new APIs
