Implement VCP support

[Disasm]

• Baud rate handling on the USB side
• UART driver (USART2)
• Automatic baud rate detection?

For the VCP remember to swap the RX/TX pair if testing :) They were accidentally swapped in the design.

[Disasm]

Huh? Connections and labels are totally correct from my perspective. Where they were swapped?

[korken89]

At the ESD chip

[Disasm]

Yes, but stlink signal names are also backwards:

Anyway, I'll be careful :)

[korken89]

Oh, maybe I got it wrong 2 times xD
