Implement PDO driver specific subclasses in PHP 8.4

[ju5t]

In PHP 8.4 there will be PDO driver specific subclasses. This allows for driver specific methods. I imagine this not being a huge improvement for most, but it does allow SQLite users to load extensions for example.

At the moment, new PDO is used when creating a connection. This will still work in 8.4.

framework/src/Illuminate/Database/Connectors/Connector.php

Lines 63 to 66 in 81a0b5b

	protected function createPdoConnection($dsn, $username, $password, $options)
	{
	return new PDO($dsn, $username, $password, $options);
	}

In 8.4 you can use PDO::connect to automatically select the driver specific class for a database.

protected function createPdoConnection($dsn, $username, $password, $options) 
{ 
    return (version_compare(phpversion(), '8.4.0', '<'))
        ? new PDO($dsn, $username, $password, $options)
        : PDO::connect($dsn, $username, $password, $options); 
} 

See: https://github.com/php/php-src/blob/php-8.4.0alpha1/UPGRADING#L299.

Would this be something to consider in 12.x? Assuming that's the first version supporting PHP 8.4. I'm happy to send a PR for it, but I am not sure what your policy is regarding new PHP versions.
