Add Composite CDC+HID device option. (#5478)

* Add Composite CDC+HID device option.

- It passes on though HID interface 8 channels received from TX
- Endpoints are reconfigured to support HID interface
- Potentially this can slow down SPI Flash transfer though CDC interface...
- This could be addressed by support for MSC when using SPI Flash (emulating FATFS)

* Different way to handle MIN redefine
