Add a nid 2 algorithm name mapping capability

Providers that link against libcrypto can just use OBJ_nid2sn() to look
up the name of an algorithm given a NID. However that doesn't work for the
FIPS provider because OBJ_nid2sn() is not available there (due to the
reliance of the code on ASN.1 types). Therefore we provider a new function
to do this mapping. For providers linking against libcrypto the new function
just wraps OBJ_nid2sn(). For the FIPS provider it has a look up for all the
NIDs known there.
