Xujian Duan 3024b82918 [fix](load)Fix wrong default value for char and varchar of reading json data (#22626) ...

If a column is defined as: col VARCHAR/CHAR NULL and no default value. Then we load json data which misses column col, the result queried is not correct:
+------+
| col |
+------+
| 1 |
+------+
But expect:
+------+
| col |
+------+
| NULL |
+------+
