Error code tables in _ssl and err_name_to_codes are no longer used

(Filing this for a PR I'll upload shortly.)

Prior to #25300, the make_ssl_data.py script used various tables, exposed in _ssl, to update the error list. After that PR, these are no longer used and we can trim that a bit. This gets them out of the way if, in the future, OpenSSL provides an API to do what the code here is doing directly. (openssl/openssl#19848)
