F6: USB glue cleanup and fixes (#666)

* USB-CDC: accepting the next data packet only if we process previous data
* USB-CDC: use USB FS packet size
* HAL-console: puts method
* Check: print assertion data
* FuriHal: rx stream free space aware CDC confirmation.
* Bootloader: pull down USB lines, leave the rest to the firmware or bootloader
* F6: cleanup and move USB code to usb-glue folder, add USB suspend/resume events to VCP, cleanup target.mk, fix missing motd message in cli when using minicom.
* F5: cleanup the rest of USB glue code, adjust LPM and Power info data in descriptor.
