bp #53050
Related PR: #40695
Problem Summary:
pr #40695 introduced the function `from_iso8601_date`, which parses the
string to get year、mouth、 day, and sets the date value through the
`set_time_unit` function.
Since `set_time_unit` lacks some judgment on mouth, it may get an
illegal date in the end, which may cause core in debug mode.
sql : `select from_iso8601_date('2023-00-01');`

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.
doc pr: https://github.com/apache/doris-website/pull/810
1. Fix memory issues in LoadStreamMgrTest.
2. Skip S3FileWriterTest by default because it depends on the environment in teamcity.
3. Fix VTimestampFunctionsTest.convert_tz_test.
this PR #22602 have check function.
only support date_trunc(column, const), so the second must be const literal
and no need to check time unit every row.
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.
1. solved the previous delayed unit test file size is too large (1.7G+) and the unit test link time is too long problem problems
2. Unify all unit tests into one file to significantly reduce unit test execution time to less than 3 mins
3. temporarily disable stream_load_test.cpp, metrics_action_test.cpp, load_channel_mgr_test.cpp because it will re-implement part of the code and affect other tests
1. Support some function alias of mod/fmod, adddate/add_data
2. Support some function of multi args: week, yearweek
3. Fix bug of multi args function call the DATETIME type not effective in DATE type

## Problem Summary:
### 1. Some code from clickhouse
**ClickHouse is an excellent implementation of the vectorized execution engine database,
so here we have referenced and learned a lot from its excellent implementation in terms of
data structure and function implementation.
We are based on ClickHouse v19.16.2.2 and would like to thank the ClickHouse community and developers.**
The following comment has been added to the code from Clickhouse, eg:
// This file is copied from
// https://github.com/ClickHouse/ClickHouse/blob/master/src/Interpreters/AggregationCommon.h
// and modified by Doris
### 2. Support exec node and query:
* vaggregation_node
* vanalytic_eval_node
* vassert_num_rows_node
* vblocking_join_node
* vcross_join_node
* vempty_set_node
* ves_http_scan_node
* vexcept_node
* vexchange_node
* vintersect_node
* vmysql_scan_node
* vodbc_scan_node
* volap_scan_node
* vrepeat_node
* vschema_scan_node
* vselect_node
* vset_operation_node
* vsort_node
* vunion_node
* vhash_join_node
You can run exec engine of SSB/TPCH and 70% TPCDS stand query test set.
### 3. Data Model
Vec Exec Engine Support **Dup/Agg/Unq** table, Support Block Reader Vectorized.
Segment Vec is working in process.
### 4. How to use
1. Set the environment variable `set enable_vectorized_engine = true; `(required)
2. Set the environment variable `set batch_size = 4096; ` (recommended)
### 5. Some diff from origin exec engine
