[issue37630] Investigate replacing SHA3 code with OpenSSL

New submission from Christian Heimes : Recent OpenSSL comes with SHA3. Now that Python is going to drop support for old OpenSSL, we can consider to use OpenSSL's SHA3 and drop the reference implementation from Python. For variable length SHAKE API, OpenSSL added EVP_MD_CTRL_XOF_LEN and
