 MDEV-37435 Make new vcols created in vcol index substitution inherit name resolution from the select_lex 
When a column or alias is the GROUP BY item, and a HAVING conjunct
depends on this column/alias only, the HAVING conjunct could contain
an Item_ref pointing to the GROUP BY Item_field.

If the column/alias happens to the be the expression of a vcol, the
GROUP BY item would be substituted with a newly created vcol
Item_field (MDEV-36132). This causes the Item_ref in HAVING to point
to the new vcol Item_field as well.

Subsequently in the HAVING to WHERE pushdown optimization, the
conjunct is moved to WHERE and fix_fields is called on it, where it
expects the vcol Item_field to have a name resolution context. So we
let the vcol Item_field inherit the context from the select_lex.
