Amit Langote 86d33987e8 SQL/JSON: Rethink c2d93c3802 
This essentially reverts c2d93c3802 except tests. The problem with
c2d93c3802 was that it only changed the casting behavior for types
with typmod, and had coding issues noted in the post-commit review.

This commit changes coerceJsonFuncExpr() to use assignment-level casts
instead of explicit casts to coerce the result of JSON constructor
functions to the specified or the default RETURNING type.  Using
assignment-level casts fixes the problem that using explicit casts was
leading to the wrong typmod / length coercion behavior -- truncating
results longer than the specified length instead of erroring out --
which c2d93c3802 aimed to solve.

That restricts the set of allowed target types to string types, the
same set that's currently allowed.
