`FileArrowScanner::get_next` returns a block when full, so it maybe contains multiple
splits in small files or crosses two splits in large files.
However, a block can only fill the partition values from one file. Different splits may be
from different files, causing the error of embed partition values.
Hash join node adds three new attributes.
The following will take an SQL as an example to illustrate the meaning of these three attributes
```
select t1. a from t1 left join t2 on t1. a=t2. b;
```
1. vOutputTupleDesc:Tuple2(a'')
2. vIntermediateTupleDescList: Tuple1(a', b'<nullable>)
2. vSrcToOutputSMap: <Tuple1(a'), Tuple2(a'')>
The slot in intermediatetuple corresponds to the slot in output tuple one by one through the expr calculation of the left child in vsrctooutputsmap.
This code mainly merges the contents of two PRs:
1. [fix](vectorized) Support outer join for vectorized exec engine (https://github.com/apache/doris/pull/10323)
2. [Fix](Join) Fix the bug of outer join function under vectorization #9954
The following is the specific description of the first PR
In a vectorized scenario, the query plan will generate a new tuple for the join node.
This tuple mainly describes the output schema of the join node.
Adding this tuple mainly solves the problem that the input schema of the join node is different from the output schema.
For example:
1. The case where the null side column caused by outer join is converted to nullable.
2. The projection of the outer tuple.
The following is the specific description of the second PR
This pr mainly fixes the following problems:
1. Solve the query combined with inline view and outer join. After adding a tuple to the join operator, the position of the `tupleisnull` function is inconsistent with the row storage. Currently the vectorized `tupleisnull` will be calculated in the HashJoinNode.computeOutputTuple() function.
2. Column nullable property error problem. At present, once the outer join occurs, the column on the null-side side will be planned to be nullable in the semantic parsing stage.
For example:
```
select * from (select a as k1 from test) tmp right join b on tmp.k1=b.k1
```
At this time, the nullable property of column k1 in the `tmp` inline view should be true.
In the vectorized code, the virtual `tableRef` of tmp will be used in constructing the output tuple of HashJoinNode (specifically, the function HashJoinNode.computeOutputTuple()). So the **correctness** of the column nullable property of this tableRef is very important.
In the above case, since the tmp table needs to perform a right join with the b table, as a null-side tmp side, it is necessary to change the column attributes involved in the tmp table to nullable.
In non-vectorized code, since the virtual tableRef tmp is not used at all, it uses the `TupleIsNull` function in `outputsmp` to ensure data correctness.
That is to say, the a column of the original table test is still non-null, and it does not affect the correctness of the result.
The vectorized nullable attribute requirements are very strict.
Outer join will change the nullable attribute of the join column, thereby changing the nullable attribute of the column in the upper operator layer by layer.
Since FE has no mechanism to modify the nullable attribute in the upper operator tuple layer by layer after the analyzer.
So at present, we can only preset the attributes before the lower join as nullable in the analyzer stage in advance, so as to avoid the problem.
(At the same time, be also wrote some evasive code in order to deal with the problem of null to non-null.)

This is an example of s3 hms_catalog:
```sql
CREATE CATALOG hms_catalog properties(
"type" = "hms",
"hive.metastore.uris"="thrift://localhost:9083",
"AWS_ACCESS_KEY" = "your access key",
"AWS_SECRET_KEY"="your secret key",
"AWS_ENDPOINT"="s3 endpoint",
"AWS_REGION"="s3-region",
"fs.s3a.paging.maximum"="1000");
```
All these params are necessary;
* support like/not like conjuncts push down to storage engine
* vectorized engine support like/not like conjuncts push down to storage engine
* support both evaluate and evaluate_vec method in like predicate
* reuse remove_pushed_conjuncts and prevent logic error during move function conjuncts
* change #ifndef to pragma once as per comments
* change enable_function_pushdown default to false

In the strict memory usage mode of STRICT_MEMORY_USE=ON, when the capacity of the vectorized Hash Table is greater than 2G, it starts to grow when 75% of the capacity is satisfied, the memory usage of the vectorized Join becomes 50% of the previous value.
STRICT_MEMORY_USE=ON` expects BE to use less memory, and gives priority to ensuring stability when the cluster memory is limited.
* [improvement](arrow) Avoid parse timezone for each datetime value
Convert arrow batch to doris block is too slow when there are datetime values.
Because we call `TimezoneUtils::find_cctz_time_zone` for each values.
