MDEV-24936 EXPLAIN for query based on table value constructor lacks info
on used subqueries
If a query was based on a table value constructor that contained subqueries
then EXPLAIN for such query did not contain any lines explaining the
execution plans of the subqueries.
This happened because
- no optimize() method was called for any subquery used by the table value
constructor when EXPLAIN command for the query was processed;
- EXPLAIN node created for the table value constructor itself did not
assume that some child nodes could be attached to it.
