[views] Use 3.25 'derived rtags' feature This allows to keep only specific rules in derived rtags and to look for other in the "parent" rtag, so that rules which are set there after the derived rtag have been constructed are still considered (if not overriden). This will avoid some rules duplication in at least the saem_ref cube. There may be a few ones that may be removed from this cube but this is not done by this commit. Using this feature requires backporting fixes done in unreleased cubicweb 3.25.3. Related to #17106806
