Asset Browser: Improved workflow for asset catalog saving

No longer save asset catalogs on blendfile save. Instead:

- extend the confirmation prompt for unsaved changes to show unsaved
  catalogs.
- In the confirmation prompt, make catalog saving explicit & optional,
  just like we do it for external images. {F10881736}
- In the Asset Browser catalog tree, show an operator icon to save the
  catalogs to disk. It's grayed out if there are no changes to save, or
  if the .blend wasn't saved yet (required to know where to save the
  catalog definitions to). {F10881743}

Much of the work was done by @Severin and reviewed by me, then we
swapped roles.
