stm32/usb: Add support to auto-detect USB interface, either FS or HS.

Browse Source 
If both FS and HS USB peripherals are enabled for a board then the active
one used for the REPL will now be auto-detected, by checking to see if both
the DP and DM lines are actively pulled low.  By default the code falls
back to use MICROPY_HW_USB_MAIN_DEV if nothing can be detected.
