Support plain php as serializer resource metadata.

[dotdevio]

Description
api-platform/core#3738 the same way we can use plain php files for symfony serializer metadata, it rlly more easy to use php constants and class names in php files instaed of yaml or xml.

Example
config/serializer.php

<?php

return [
	App\Model\User::class => [
		'attributes' => [
			'uuid' => [
				'groups' => App\ApiConstants::READ,
			],
		],
	],
];

Thank you for this suggestion.
There has not been a lot of activity here for a while. Would you still like to see this feature?

Friendly ping? Should this still be open? I will close if I don't hear anything.
