common: Enhance memory mapping safety and debugging

- Reduce max_memory_size from 512GB to 1GB for safer allocation limits
- Add memory operation logging for debugging purposes
- Implement MapMemory() with additional safety checks and large allocation handling
- Add validation checks for memory mappings
- Introduce chunked allocation strategy for large memory requests
- Add detailed error logging for memory operations
