SIENTIAPDE-1231

Add memory management function to model_repository.py

- Introduced `force_memory_release` function to enhance memory management by triggering garbage collection and attempting to release unused memory.
- Utilized `ctypes` to call `malloc_trim` for further memory optimization, improving overall performance during model operations.
