error code
```C++
return creator_without_type::create<AggregateFunctionForEach>(transform_arguments, true,
nested_function);
```
"transform_arguments is an internal type of array. All internal types of
the array are null, so an array that is not null was mistakenly treated
as a null array."

<!--Describe your changes.-->
pick (#37078)
In previous versions, we adopted the strategy of reading the object
address for Oracle's raw type, which would lead to unstable and
meaningless results. Here I changed it to read hexadecimal or UTF8
pick https://github.com/apache/doris/pull/37062
1. revert https://github.com/apache/doris/pull/25097. we decide to rely
on OS. not maintain independent tzdata anymore to keep result
consistency
2. refactor timezone load. removed rwlock.
before:
```sql
mysql [optest]>select count(convert_tz(d, 'Asia/Shanghai', 'America/Los_Angeles')), count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) from dates;
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| count(convert_tz(cast(d as DATETIMEV2(6)), 'Asia/Shanghai', 'America/Los_Angeles')) | count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| 16000000 | 16000000 |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
1 row in set (6.88 sec)
```
now:
```sql
mysql [optest]>select count(convert_tz(d, 'Asia/Shanghai', 'America/Los_Angeles')), count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) from dates;
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| count(convert_tz(cast(d as DATETIMEV2(6)), 'Asia/Shanghai', 'America/Los_Angeles')) | count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| 16000000 | 16000000 |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
1 row in set (2.61 sec)
```
3. now don't support timezone offset format string like 'UTC+8', like we
already said in
https://doris.apache.org/docs/dev/query/query-variables/time-zone/#usage
4. support case-insensitive timezone parsing in nereids.
5. a bug when parse timezone using nereids. should check DST by input,
but wrongly by now before. now fixed.

<!--Describe your changes.-->
All timestamp/datetime parsing in Doris is controlled by the session
variable `time_zone`.
Apply it also to interface of `TimeUtils` in FE.

## Proposed changes
```
mysql [test]>set DEBUG_SKIP_FOLD_CONSTANT = true;
Query OK, 0 rows affected (0.00 sec)
mysql [test]>select cast(unix_timestamp("2024-01-01",'yyyy-MM-dd') as bigint);
+------------------------------------------------------------+
| cast(unix_timestamp('2024-01-01', 'yyyy-MM-dd') as BIGINT) |
+------------------------------------------------------------+
| 1704038400000000 |
+------------------------------------------------------------+
```
now
```
mysql [test]>select cast(unix_timestamp("2024-01-01",'yyyy-MM-dd') as bigint);
+------------------------------------------------------------+
| cast(unix_timestamp('2024-01-01', 'yyyy-MM-dd') as BIGINT) |
+------------------------------------------------------------+
| 1704038400 |
+------------------------------------------------------------+
1 row in set (0.01 sec)
```
The column does not have a scale set, but the cast uses the scale to
perform the cast.
