openssl_privatekey: add ECC support (#49416)
* Add cryptography backend for openssl_privatekey. * Adding ECC support. No support for X25519 and X449, since they don't support serialization. * Improve finterprint calculation to work with Python 3. * Add fingerprint check. * Fix typo. * Use separate curve option for elliptic curves, and use type 'ECC'. * Using curve names as defined in IANA registry. * Bump minimal supported cryptography version. Older versions might work as well, but I couldn't test them. * Improve documentation.
