Attached 43rd version of the patches.

The previous patch #4 ("Add function formats") was removed.
Instead, introduced new executor node JsonCtorExpr which is used to wrap
SQL/JSON constructor function calls (FuncExpr, Aggref, WindowFunc).

Also, JsonIsPredicate node began to be used as executor node.
This helped to remove unnecessary json[b]_is_valid() user functions.
