Add a custom USB driver for ARM (#2750)

Browse Source 
* Copy Chibios serial_usb_driver into the chibios/protocol

It's renamed to usb_driver to avoid name conflicts

* Make the usb driver compile

* Disable ChibiOS serial usb driver for all keyboards

* Change usb_main to use QMKUSBDriver

* Initialize the usb driver buffers

* Add support for fixed size queues

* Fix USB driver initialization

* Don't transfer an empty packet for fixed size streams
