SSL Connection: combine SSL_set_ex_data and SSL_set_app_data

Title: Combine SSL Connection's SSL_set_ex_data and SSL_set_app_data

Description:
PR #9172 introduces additional SSL_set_ex_data to be able to update SslExtendedSocketInfo during SSL validation.
This issue is to refactor the new SSL_set_ex_data and existing SSL_set_app_data to combine to a single SSL_set_app_data.

Currently:
SSL_set_app_data: The ContextImpl's const Network::TransportSocketOptions* options set by the ContextImpl but only if (options && !options->verifySubjectAltNameListOverride().empty()) when the SslSocket is created
SSL_set_ex_data: The SslSocketInfo::SslExtendedSocketInfo member set when the SslSocket is subsequently moved to be owned by the constructed SslSocketInfo
