Remove more ASN1_BIT_STRING API

This removes ASN1_BIT_STRING_name_print(), ASN1_BIT_STRING_{num,set}_asc().
Before trust was properly handled using OIDs, there was a period where it
used bit strings. The actual interfaces used in openssl x509 were removed,
but the functions they wrapped remained unused for the next 24 years.
