Add SSL cert/key support to MySQL schema dump and load (#57821)

[HeathNaylor]

Fixes #57821

When using PDO SSL client certificate options MYSQL_ATTR_SSL_CERT and MYSQL_ATTR_SSL_KEY, the mysqldump and mysql commands were not getting the corresponding --ssl-cert and --ssl-key flags. This causes auth failures for users with client certs.

I added --ssl-cert and --ssl-key CLI flag support to MySqlSchemaState::connectionString() when PDO::MYSQL_ATTR_SSL_CERT and PDO::MYSQL_ATTR_SSL_KEY options are configured. MariaDbinherits the fix automatically.

I tested this on MySQL 9.3.0 by generating self signed certs and required X509 for a new user (CREATE USER 'laravel_ssl'@'localhost' IDENTIFIED BY 'secret' REQUIRE X509). I configured the config/database.php and added the MYSQL_ATTR_SSL_CA, MYSQL_ATTR_SSL_CERT, MYSQL_ATTR_SSL_KEY options. I then ran php artisan schema:dump and php artisan migrate which succeeded over TLS.
