[12.x] Fix| Fallback to PDO::const when Mysql::const not available

[YasserB94]

Issue

Laravel Framework 12.x references the php 8.4 Mysql::ATTR_SSL_VERIFY_SERVER_CERT const.
Yet, since symfony/polyfill-php84:v1.38.0 it is no longer available (bug #590 PHP can be built without PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT )

Changes

• Check if the constant exists, if it does not we fallback to php7.0 PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT.

This seems to be the simplest fix for this issue

Exception

[  Undefined constant Pdo\Mysql::ATTR_SSL_VERIFY_SERVER_CERT ]

vendor/laravel/framework/src/Illuminate/Database/Schema/MySqlSchemaState.php:133
    129▕         if (isset($config['options'][Mysql::ATTR_SSL_KEY])) ***
    130▕             $value .= ' --ssl-key="$***:LARAVEL_LOAD_SSL_KEY***"';
    131▕         ***

    135▕                 $value .= ' --ssl-mode=DISABLED';
    136▕             *** else ***
    137▕                 $value .= ' --ssl=off';

How to reproduce

• Setup a fresh laravel 12 project on php8.3
• Bump symfony/polyfill-php84 to the latest version

Tests

• I added the same check in the tests where I found reference to Pdo\Mysql::ATTR_SSL_VERIFY_SERVER_CERT

I think https://github.com/symfony/polyfill/releases/tag/v1.38.1 should fix this. Can you check that? If so, adding a conflict with the specific version 1.38.0 here should suffice.
