[Maintenance] USB HID control packet as struct (#21688)

* ChibiOS: USB HID control request as dedicated struct

Instead of accessing the raw USB setup packet and documenting the values
as the corresponding USB HID control request fields we introduce a
struct that allows direct access to the fields. This is safer and self
documenting.

* Rename usb_request.h to usb_types.h

In the future all shared USB data types can live in this file.
