DEV: Add new bookmarks:changed app event (#14674)

This new app event will fire whenever a bookmark is created,
edited, or deleted for a post or topic, and replaces these old
app events which had inconsistent APIs:

* page:bookmark-post-toggled
* topic:bookmark-toggled

When the event is triggered, the arguments are in this order:

1. bookmark - The bookmark record created or changed. Will be null
              if the bookmark was deleted.
2. target   - Object with target (post or topic) and targetId (post ID
              or topic ID)
