  [flang][OpenACC] generate Destroy region to free memory of private and firstprivate if needed (#162702)

This patch extends the MappableTypeInterface to:
- allow genPrivateInit to indicate that a Destroy region will be needed.
- add genPrivateDestroy to generate the destruction code
- Implement both interfaces in FIR
- Update OpenACC lowering to generate the Destroy region when needed
using those interfaces.
