[TASK] SOLR_RELATION respect enableFields on MM-related records

The RelationHandler doesn't respect enableFields of the table
behind the MM-relation. Because this has been in place for quite a
long time. A new option respectEnablefieldsMM is introduced, which
can be set as configuration parameter when using SOLR_RELATION to
filter e.g. hidden categories.

Resolves #65692
