SQL/JSON: Validate values in ON ERROR/EMPTY clauses
Currently, the grammar allows any supported values in the ON ERROR
and ON EMPTY clauses for SQL/JSON functions, regardless of whether
the values are appropriate for the function. This commit ensures
that during parse analysis, the provided value is checked for
validity for the given function and throws a syntax error if it is
not.
While at it, this fixes some omissions in the documentation of the
ON ERROR/EMPTY clauses for JSON_TABLE().
