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

* for Human Interface Devices (HID) Version 1.11 Jun 27, 2001".
|

* - The Boot Interface Subclass
|
||||
* - The Mouse protocol
|

* - Usage Page : Generic Desktop
|

*
|
||||
* @note In HS mode and when the DMA is used, all variables and data structures
|
||||
* dealing with the DMA during the transaction process should be 32-bit aligned.
