All media_download_all: cache tags should be invalidate during media deletion

Problem/Motivation

All media_download_all: cache tags should be invalidate during media deletion.

Steps to reproduce

• Create node with media field
• Add 2 medias
• Download all media
• Remove first media using contextual link / single media page or media manager page
• Download all media
• You can still see 2 medias because MDA does not know about any actions under your media entities.

Proposed resolution

• Create service to get all media_download_all: tags from DB and invalidate them during media deletion in hook_media_delete

public function invalidateTags() {
    $connectionSettings = Database::getConnection();
    $prefix = $connectionSettings->getConnectionOptions()['prefix'];
    $tags = $this->database->query("SELECT * FROM {$prefix}cache_default WHERE cid LIKE '%media_download_all:%'")
      ->fetchAll();

    foreach ($tags as $tag) {
      $cid = $tag->cid;
      $cache = $this->cache->get($cid);
      if ($cache) {
        $cached_files = $cache->data;
        if (!empty($cached_files)) {
          foreach ($cached_files as $file) {
            unlink($file);
          }
        }
        $this->cache->delete($cid);
      }
    }
  }
