TagAware cache is not profiled in the profiler

[rbaarsma]

Symfony version(s) affected: 4.4.1 (probably also 3.4 and 5.0)

Description
When using a cache adapter with tags: true, and typehinting this adapter with TagAwareCacheInterface instead of the CacheItemPoolInterface (PSR-6), and running on env=dev or env=test, the TraceableAdapter is not used, but instead the Symfony\Component\Cache\Adapter\TagAwareAdapter is injected.

Because of this, the subsequent cache changes are not profiled.

How to reproduce

framework:
    cache:
        pools:
            app.cache_pool:
                adapters:
                    - cache.adapter.array
                    - cache.adapter.apcu
                    - cache.adapter.redis
                tags: true

use Symfony\Contracts\Cache\TagAwareCacheInterface;

class TestController 
{
  /** @var TagAwareAdapterInterface */
  private $appCachePool;

  public function __construct(TagAwareCacheInterface $appCachePool) 
  {
    echo get_class($appCachePool); // outputs Symfony\Component\Cache\Adapter\TagAwareAdapter
    $this->cache = $appCachePool;
  }

  /** @Route("/test") */
  public function test()
  {
    // works, but not in profiler
    $this->cache->get('somkey', function (ItemInterface $item) {
        $item->tag('sometag');
        return true;
    });
    $this->cache->invalidateTags('sometag');
  }
}

Good catch. Would you be able to send a PR to fix the wiring?
