Allow to rewrite filename with a custom name when it's download

I got a request to implement this - we want to be able to replace media files with the same filename. I'm ok with media adding _1 for versioning and caching, but it would be great if it could be downloaded with a clean filename. Generating that from the media name makes sense.

I imagine we need this in place to get it working: https://www.drupal.org/project/media_entity_download/issues/3351543 ✨ Introduce hook to alter the download response Active
This is a similar issue (is it a duplicate?) https://www.drupal.org/project/media_entity_download/issues/3176548 →

What are the blockers here? If one of those patches works, it may not be too difficult to get the base case for this working.

Depending on how specific we want to alter the response, if this gets approved: https://www.drupal.org/project/media_entity_download/issues/3418334 ✨ Use filename in download RTBC .

We could also simply create a hook for the filename like:
$filename = $this->moduleHandler()->invokeAll('file_download_name', [$media, file]);

And then add a default return for the hook like: $filename = $file->label();

Hi, I added JavaScript to prompt users to rename files before download and added checkbox in FieldFormatter to use this functionality. Please review the attached patch.
