stm32/usb: Add "msc" kw-arg to pyb.usb_mode to select MSC logical units.

Browse Source 
With this the user can select multiple logical units to expose over USB MSC
at once, eg: pyb.usb_mode('VCP+MSC', msc=(pyb.Flash(), pyb.SDCard())).  The
default behaviour is the original behaviour of just one unit at a time.
