…ght, append_trailing_char_if_absent (#49127)
The url_encode function previously performed a modulus operation on a
signed number. Converting it to an unsigned number will fix the issue.
```
before
mysql> select url_encode('编码');
+----------------------+
| url_encode('编码') |
+----------------------+
| %5.%23%0-%5.%10%/( |
+----------------------+
now
mysql> select url_encode('编码');
+----------------------+
| url_encode('编码') |
+----------------------+
| %E7%BC%96%E7%A0%81 |
+----------------------+
```
The strright function did not calculate the length according to the
number of UTF-8 characters.
```
before
mysql> select strright("你好世界",5);
+----------------------------+
| strright("你好世界",5) |
+----------------------------+
| |
+----------------------------+
now
mysql> select strright("你好世界",5);
+----------------------------+
| strright("你好世界",5) |
+----------------------------+
| 你好世界 |
+----------------------------+
```
he case of inputting a UTF-8 character was not considered.
```
mysql> select append_trailing_char_if_absent('中文', '文');
+-------------------------------------------------+
| append_trailing_char_if_absent('中文', '文') |
+-------------------------------------------------+
| NULL |
+-------------------------------------------------+
now
mysql> select append_trailing_char_if_absent('中文', '文');
+-------------------------------------------------+
| append_trailing_char_if_absent('中文', '文') |
+-------------------------------------------------+
| 中文 |
+-------------------------------------------------+
```
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.
* Revert "[fix](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)"
This reverts commit 397cc011c4f1ba5a25c770258c13f1cd3f28b47d.
* [fix-resubmit](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)
ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided.
Solved: 192/256 supports calculation without init vector
For other algorithms, an error should be reported when there is no init vector
Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.
Reference: https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-decrypt
Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found

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

## 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
