[Simh] EXT : VAX SDL support?

VAXwindows was a layered product (like just about everything DEC sold for
VMS).  Without it a VAXstation of that era wouldn't be very user friendly,
but it would boot happily enough.  However all my VAX software CD-ROMs are
from V5.3(?) onwards so I very much doubt the VAXwindows product is there.
