feat(emulator): implement gRPC control server and emulator commands

- Added `AgentControlServer` to manage gRPC connections for emulator control.
- Introduced `EmulatorServiceImpl` with methods for starting, stopping, and controlling the emulator, including button presses and memory operations.
- Created new command handlers for pressing, releasing, and holding emulator buttons.
- Updated CMake configuration to include new source files and proto definitions for the emulator service.

Benefits:
- Enhanced control over the emulator through gRPC, allowing for remote interactions.
- Improved modularity and maintainability of the emulator's command handling.
- Streamlined integration of new features for emulator control and state inspection.
