Refactor USB and application task handling

- Updated USB OTG FS interrupt priority to the highest level for improved responsiveness.
- Refactored application task to use a flow control structure for better timing management.
- Removed unnecessary FreeRTOS dependencies from shell port implementation.
- Disabled shell task loop for non-RTOS environments, allowing for more flexible shell usage.
- Adjusted flow tick rate for finer control over timing.
- Cleaned up project configuration to remove unused FreeRTOS task definitions and streamline NVIC settings.
