Support json array with nereids bool
now :
```
set enable_nereids_planner=true;
mysql> SELECT json_array(1, "abc", NULL, TRUE, '10:00:00');
+----------------------------------------------+
| json_array(1, 'abc', NULL, TRUE, '10:00:00') |
+----------------------------------------------+
| [1,"abc",null,false,"10:00:00"] |
+----------------------------------------------+
1 row in set (0.02 sec)
```
nereids boolean is "true"/"false" is not '0' /'1' , so we always get false
