Finds a script handle for the selected block metadata field.

Detects when a path to a file was provided and optionally finds a corresponding asset file with details necessary to register the script. The handle is taken from the asset file when it provides one, and is otherwise generated automatically. It returns the unprocessed script handle when a handle rather than a path was given.
