Fix panic when parsing SSH SK pubkeys #1712

This is because these pubkey types do not implement ssh.CryptoPublicKey, which causes a panic when we try to do a type assertion.

Also realized we weren't handling SSH certs, so now we extract the pubkey from the cert before trying to parse it.

Had to reimplement parsing the SK pubkeys because there is no other way to extract the raw pubkey from it. After golang/go#62518, this will get cleaned up.
