Add data buffering: backport of major buffering features from g4: CAN TX buffering, CDC RX buffering. No USB TX buffering yet.

Fix USB priority preventing CAN TX from timing out
...
The blocking CAN implementation relies on SysTick for its timeout. USB had a higher priority than Systick, so the TX never timed out, causing the serial port to hang indefinitely.

Port to new HAL, fixes USB issues. Revert to blocking CAN RX/TX. Add unique serial number from chip UID.

Appears that Receive_IT rearm call is returning HAL_BUSY as the CAN module is locked on txing. Need to resolve HAL issue.

Defer some work to the main loop. Deferring slcan parse from usbd_cdc_if receive interrupt fixes freezing but CANables stop talking.
