Fix AP4 4.3.x and Symfony 8.x compatibility

- Migrate API Platform resource config from XML files to PHP attributes
  (Form, Collection, PageDataMetadata, MediaObject, ResourceMetadata) and
  switch DependencyInjection mapping to directory-based paths
- Fix Symfony\Component\Serializer\Annotation\Groups import to
  Symfony\Component\Serializer\Attribute\Groups across all affected classes
- Fix Count and Length constraint constructors to use named arguments
  (array-style constructor removed in Symfony 8.x)
- Add api_sub_level context when normalizing ResourceMetadata to prevent
  PartialCollectionViewNormalizer injecting pagination view into array
  properties (e.g. mercureSubscribeTopics) when request URI has query params
- Remove routePrefix from PageDataMetadata ApiResource to avoid double
  prefix with RoutingPrefixResourceMetadataCollectionFactory in AP4 4.x
