Merge ChibiOS and LUFA descriptor support (#2362)

* Move lufa descriptor to protocol/usb_descriptor

* Try to compile usb_descriptor on ChibiOS

* Add lufa_utils for ChibiOS

Lufa USB descriptors for ChibiOS

* More lufa_util compatibility fixes

* First compiling version of shared USB descriptor

* Send the usb descriptors

* Fix the CONSOLE output on ChibiOS

* Add errors for unsupported interfaces

* Enable support for vitual serial port USB descriptors

* Implement virtual serial port for ChibiOS

* Cleanup the lufa_utils

Use the default lufa header files

* Add raw hid support for ChibiOS

This is completely untested

* Enable midi compilation on ChibiOS

* Move midi functionality out of lufa.c

* Don't register sysex callback when not needed

* ChibiOS compilation fixes

* Update ChibiOS submodule

* Fix the Midi USB descriptor

It didn't work properly when both Midi and Virtual serial port was enabled.

* Add MIDI support for ChibiOS

* Fix USB descriptor strings on ChibiOS

* Use serial usb driver for raw hid

* Generalize the ChibiOS stream like drivers

This makes the initialization much more simple and eliminates a lot of
the code duplication.

* Convert console output to chibios stream driver

* Fixes for ChibiOS update

* Update the ChibiOS contrib submodule

To include the usb data toggle synchronization fixes

* Fix duplicate reset enumeration on ChibiOS

* Add missing include

* Add number of endpoints check for ChibiOS

* Enable serial USB driver on all keyboards

* Add missing includes when API is enabled withot midi

* Add another missing inlcude
