MDEV-7474: Semi-Join's DuplicateWeedout strategy skipped ...bb-10.0-mdev7474
JOIN::cur_dups_producing_tables was not maintained correctly in
the cases of greedy optimization (search_depth > n_tables).
Moved it to POSITION structure where it will be maintained automatically.
Removed POSITION::prefix_dups_producing_tables since its value can now
be calculated.
