Permalinks: Prevent attachment pages 404ing following [49563].

Browse Source 
This largely reverts [49563] due to attachment pages returning 404: File not found errors when they use the `inherit` status.

Permalink changes to attachment pages are retained when they are descendants of trashed or deleted posts.

Props Toro_Unit, helen, johnbillion, peterwilsoncc.
Fixes #51776.
See #5272.
