Improve generateAndLinkZipFile function

Jonathan McLaughlinrequested to merge
issue/vbo_media_export-3530883:1.0.x into 1.0.x
  • Module should use a sub-directory inside of private:// instead of leaving the files in the top-level directory.
  • Create a File entity for the zip file so that implementations of hook_file_download can use the entity.
  • Mark the File entity temporary so that it will be deleted by the file module's garbage collection (file_cron)
  • Using a File entity improves security because only the creator of the File entity can download the file (I think).
