Block Directory: Ensure scripts can depend on another script handles

[gziolo]

Description

As of today, it's possible to install blocks listed in the Block Directory using the scripts returned by the API. However, the limitation is that those scripts can depend only on script handles that are used by the block editor. The idea is that it should be also possible to use custom script handles for those scripts and there would be a way to inject them on the frontend.

Something like this could work really well

add_filter( 'script_loader_tag', function( $tag, $handle ){
   $tag = str_replace( '<script ', '<script data-handle="'.handle.'" ', $tag );
   return $tag;
});

What would be an example scenario that we are prepping for?

I think this is not an issue anymore after #22721/#23407 and #24117 — assets are pulled from a separate editor page so that all dependencies and inline scripts are loaded. If I'm misunderstanding the original issue, it can be reopened.

Sounds good. I haven't seen some of the PRs referenced. If there is more work necessary, we can always file a more targeted issue.
