a498463ab5 [feature-wip](array-type)support select ARRAY data type on vectorized engine (#8217) (#8584)
Usage Example:
1. create table for test;
```
`CREATE TABLE `array_test` (
  `k1` tinyint(4) NOT NULL COMMENT "",
  `k2` smallint(6) NULL COMMENT "",
  `k3` ARRAY<int(11)> NULL COMMENT ""
) ENGINE=OLAP
DUPLICATE KEY(`k1`)
COMMENT "OLAP"
DISTRIBUTED BY HASH(`k1`) BUCKETS 5
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"in_memory" = "false",
"storage_format" = "V2"
);`
```

2. insert some data
```
`insert into array_test values(1, 2, [1, 2]);`
`insert into array_test values(2, 3, null);`
`insert into array_test values(3, null, null);`
`insert into array_test values(4, null, []);`
```

3. open vectorized
`set enable_vectorized_engine=true;`

4. query array data
`select * from array_test;`
+------+------+--------+
| k1   | k2   | k3     |
+------+------+--------+
|    4 | NULL | []     |
|    2 |    3 | NULL   |
|    1 |    2 | [1, 2] |
|    3 | NULL | NULL   |
+------+------+--------+
4 rows in set (0.061 sec)

Code Changes include:
1. add column_array, data_type_array codes;
2. codes about data_type creation by Field, TabletColumn, TypeDescriptor, PColumnMeta move to DataTypeFactory;
3. support create data_type for ARRAY date type;
4. RowBlockV2::convert_to_vec_block support ARRAY date type;
5. VMysqlResultWriter::append_block support ARRAY date type;
6. vectorized::Block serialize and deserialize support ARRAY date type;

82f421a019 [fix](brpc-attachment) Fix bug that may cause BE crash when enable transfer_data_by_brpc_attachment (#7921)
This PR mainly changes:

1. Fix bug when enable `transfer_data_by_brpc_attachment`

    In `data_stream_sender`, we will send a serialized PRowBatch data to multiple Channels.
    And if `transfer_data_by_brpc_attachment` is enabled, we will mistakenly clear the data in PRowBatch
    after sending PRowBatch to the first Channel.
    As a result, the following Channel cannot receive the correct data, causing an error.

    So I use a separate buffer instead of `tuple_data` in PRowBatch to store the serialized data
    and reuse it in multiple channels.

2. Fix bug that the the offset in serialized row batch may overflow

    Use int64 to replace int32 offset. And for compatibility, add a new field `new_tuple_offsets` in PRowBatch.

## 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

Remove unused LLVM related codes of directory (step 4):be/src/runtime (#2910)

there are many LLVM related codes in code base, but these codes are not really used.
The higher version of GCC is not compatible with the LLVM 3.4.2 version currently used by Doris.
The PR delete all LLVM related code of directory: be/src/runtime
