Merge branch 'ml/crypto/add-ripemd160-digest/OTP-10667'

* ml/crypto/add-ripemd160-digest/OTP-10667:
  fix crypto ripemd160 tests to use hash_init family
  fix ripemd160 to use hash_init family and add documentation
  fix missing defines for RIPEMD160_CTX_LEN and RIPEMD160_LEN
  add ripemd160 support to crypto
