Remove old HAL components and refactored GPS-related code (#583)

- Added generic GPS/GNSS support with device detection, configuration, and persistent settings.
- Improved device and module lifecycle management.
- Added flexible filesystem locking support for displays and storage.
- Improved display-idle and keyboard backlight handling.
- Updated architecture, driver, module, testing, and licensing documentation.
- Removed old HAL device and related code.
