crypto: sm3 - create SM3 stand-alone library

mainline inclusion
from mainline-v5.18-rc1
commit eb90686d
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I50ABL



--------------------------------

Stand-alone implementation of the SM3 algorithm. It is designed
to have as little dependencies as possible. In other cases you
should generally use the hash APIs from include/crypto/hash.h.
Especially when hashing large amounts of data as those APIs may
be hw-accelerated. In the new SM3 stand-alone library,
sm3_transform() has also been optimized, instead of simply using
the code in sm3_generic.
