Support the new 'moved_files' key for updating libraries_overrides

Drupal version

10.3.0+

Drupal Rector version

Problem / Motivation

📌 Add a deprecation support for library-overrides Active adds a new 'moved_files' key to library definitions, which lists any files that have been moved to the library from the current one.

It may be possible to parse this list for core libraries, then parse the .info.yml for themes, then warn if the theme is overriding any files that have been moved.
