Summary

This PR fixes/implements the following bugs

  • USB CDC Serial does not work on NUCLEO_L073RZ

Describe the bug
The bug is very similar to #479 for Discovery L072CZ
I've manually applied this patch 59673c9 to NUCLEO_L073RZ and now it works nicely as well.

To Reproduce
Enable "USB CDC" in Arduino_STM32 menu settings.
Connect NUCLEO_L073RZ's PA11/PA12 to a USB host.
The host reports that:
device not accepting address 61, error -32

This PR is just intended to apply one known good L072CZ fix onto the L073RZ target.

Thanks @lyusupov
The USB support was introduced later.
And as by default the board does not have USB port, it was not enabled by default.
