service: mm: Refactor Memory Management service implementation

Refactors the MM (Memory Management) service implementation with improved:

- Session management using a vector of Session objects instead of global vars
- Type safety with proper enums and member encapsulation
- Error handling with consistent patterns
- Modern C++ features (std::erase_if, std::find_if, emplace_back)
- Logging with detailed debug messages
- Code organization and const correctness

Key changes:
- Add Session class with proper encapsulation
- Add EventClearMode enum (Manual = 0, Auto = 1)
- Update Module enum naming for consistency
- Implement proper session tracking and lookup
- Add detailed parameter logging
- Use modern C++ algorithms for session management

The implementation now properly handles multiple sessions and matches
the documented nn::mmnv::IRequest interface more closely.
