fix heap-use-after-free
The OrcReader has a internal FileInputStream, If the file is empty, the memory of FileInputStream will leak.
Besides, there is a Statistics instance in FileInputStream. FileInputStream maybe delete if the orc reader
is inited failed, but Statistics maybe used when orc reader is closed, causing heap-use-after-free error.
Potential memory leak
When init file scanner in file scan node, the file scanner prepare failed, the memory of file scanner will leak.
segcompaction is async and in parallel with load job. If the load job is
canncelling, memory structures will be destroyed and cause segcompaction
crash. This commit will wait segcompaction finished before destruction.
* [enhancement](stream load pipe) using queryid or load id to identify stream load pipe instead of fragment instance id
NewLoadStreamMgr already has pipe and other info. Do not need save the pipe into fragment state. and FragmentState should be more clear.
But this pr will change the behaviour of BE.
I will pick the pr to doris 1.2.3 and add the load id to FE support. The user could upgrade from 1.2.3 to 2.x

In #16343, we split the timeout variable into two ones (one is for query and another is for insertion).
The function `ConnectProcessor::handleQuery` uses the corresponding session variable to change the timeout for the queries requested by MySQL client. However, the function `StmtExecutor::handleInsert` doesn't use the session variable to change the timeout, so we can't change the timeout for the CTAS and MTMV insertion job.
Reason: column_name[k5], decimal value is not valid for definition, value=123.123, precision=9, scale=3, min=-999999.999, max=-999999.999; . src line [];

generate data and queries support specify SCALE,
create table may need to be edited handly to specify BUCKETS or change int to bigint if SCALE is too big.

1. The first property is `only_specified_database`:
In the past, `Jdbc Catalog` will synchronize all database from source database.
Now we add a parameter called `only_specified_database` to jdbc catalog to allow only the specified database to be synchronized, eg:
```sql
create resource if not exists ${resource_name} properties(
"type"="jdbc",
"user"="root",
"password"="123456",
"jdbc_url" = "jdbc:mysql://172.18.0.1:${mysql_port}/doris_test?useSSL=false",
"driver_url" = "https://doris-community-test-1308700295.cos.ap-hongkong.myqcloud.com/jdbc_driver/mysql-connector-java-8.0.25.jar",
"driver_class" = "com.mysql.cj.jdbc.Driver",
"only_specified_database" = "true"
);
```
if `only_specified_database` is `true`, jdbc catalog will only synchronize the database which is specified in `jdbc_url`.
2. The second property is `lower_case_table_names`:
This property will synchronize jdbc external data source table names in lower case.
```sql
create resource if not exists ${resource_name} properties(
"type"="jdbc",
"user"="doris_test",
"password"="123456",
"jdbc_url" = "jdbc:oracle:thin:@172.18.0.1:${oracle_port}:${SID}",
"driver_url" = "https://doris-community-test-1308700295.cos.ap-hongkong.myqcloud.com/jdbc_driver/ojdbc8.jar",
"driver_class" = "oracle.jdbc.driver.OracleDriver",
"lower_case_table_names" = "true"
);
```
1. could not use static INSTANCE for FoldConstantOnBE rule, because it is stateful
2. if expression root is Alias, should use its child to do const collection
This CL mainly changes:
Support specifying csv schema manually in s3/hdfs table valued function
s3 (
'URI' = 'https://bucket1/inventory.dat',
'ACCESS_KEY'= 'ak',
'SECRET_KEY' = 'sk',
'FORMAT' = 'csv',
'column_separator' = '|',
'csv_schema' = 'k1:int;k2:int;k3:int;k4:decimal(38,10)',
'use_path_style'='true'
)
Add new session variable dry_run_query
If set to true, the real query result will not be returned, instead, it will only return the number of returned rows.
mysql> select * from bigtable;
+--------------+
| ReturnedRows |
+--------------+
| 10000000 |
+--------------+
This can avoid large result set transmission time and focus on real execution time of query engine.
For debug and analysis purpose.
