First step of the remaining structure/media pool extension point cleanup.

MEDIA_MOVED → MediaUpdated

MEDIA_MOVED was dispatched by the pages, not by the handler:

• the detail form saved the category via MediaHandler::edit() (dispatching MediaUpdated) and dispatched MEDIA_MOVED afterwards by hand,
• the bulk move of the media list updated rex_media directly, bypassing the handler and thus MediaUpdated.

Unlike articles (separate operation and permission, hence ArticleMoved), moving media is part of editing them. So the bulk move now calls MediaHandler::edit() with just the category_id as well, and MEDIA_MOVED is removed: a move is a MediaUpdated whose previous state has a different categoryId. A separate MediaMoved would have to be dispatched in addition to MediaUpdated for the detail form, i.e. two events for one change.

The rector rule maps MEDIA_MOVED to MediaUpdated, like ART_META_UPDATED → ArticleUpdated in #6778. Usage in public addons: none found except redaxo.org.

GENERATE_FILTER removed

It let extensions modify the generated PHP code of the content cache. The rendered output can be modified via ART_CONTENT, SliceOutput or OUTPUT_FILTER. Usage in public addons: none found except redaxo.org.

Tested

Bulk move into a media category and moving back via the detail form, both in the backend.
