…m tagged providers (nicolas-grekas) This PR was squashed before being merged into the 8.2 branch.

Bundles can tag iterable services to provide classes for PropertyInfo, Serializer, and Validator warmup. The Serializer warmer removes duplicate fallback entries after writing its PHP array. With api-platform/core#8847 on Symfony 8.2, the test app's system pool has 992 files after warmup, down from 14,389 before these warmers.

Instead of #8846.
API Platform warms PropertyInfo and default property metadata into PHP arrays. It also supplies resource classes to Symfony's PropertyInfo, Serializer, and Validator warmers. With symfony/symfony#68155 on Symfony 8.2, the test app's system pool falls from 14,389 to 992 files after
cache:warmup. The property warmer saves 2,333 inodes; OpenAPI export still creates 19,996 files for additional metadata keys.
