yang: leaf-list needs to use ordered-by user
RFC 7950 defines an ordered-by clause when a list needs to maintain its order: https://datatracker.ietf.org/doc/html/rfc7950#section-7.7.7 The default ordering is "system", which means the user specified order doesn't need to be preserved. Prior to this libyang commit there was no difference between system and user ordering: CESNET/libyang@6cf1d16 Since SONiC depends on list ordering being maintained, either explicitly due to the order actually mattering, or implicitly due to the reverse translation performed during config valiation, we need to tag all leaf-list references as `ordered-by user`.
