Support two hll functions:
- hll_from_base64
Convert a base64 string(result of function hll_to_base64) into a hll.
- hll_to_base64
Convert an input hll to a base64 string.
in some case, we has code
```
if (_join_op == TJoinOp::RIGHT_OUTER_JOIN || _join_op == TJoinOp::FULL_OUTER_JOIN) {
_probe_column_convert_to_null = _convert_block_to_null(*input_block);
}
```
then do next function like cast , but in function cast we assume block column is same with from_type.which will make status error
* [Fix](partial-update) Fix partial update fail when the datetime default value is 'current_time' (#32926)
* Problem: When importing data that includes datetime with a default value of current time for partial column updates, the import fails.
Reason: Partial column updates do not handle the logic for datetime default values.
Solution: During partial column updates, when the default value is set to current time, read the current time from the runtime state and write it into the data.
* [Enhancement](partial update)Add timezone case for partial update timestamp #33177
* [fix](partial update) Support partial update when the date default value is 'current_date'. This PR is a extension of PR #32926. (#33394)

This PR aims to enhance the compatibility of BI tools (such as Dbeaver, DataGrip) when using the mysql connector to connect to Doris, because some BI tools query some tables in the mysql database. In our tests, the user and procs_priv tables were mainly queried. This PR adds these two tables and adds actual data to the user table. However, please note that most of the fields in the user table are in Doris' own format rather than mysql format, so it can only ensure that the BI tool is querying No error is reported when accessing these tables, which does not guarantee that the data is completely displayed, and the tables under Doris's mysql database do not support data modification.
Thanks to @liujiwen-up for assisting in testing
During the renaming of `JdbcCatalog`, I noticed that the `jdbcClient` was being closed,
resulting in exceptions during subsequent queries. This happens because the `removeCatalog`
method is invoked when changing the name, which in turn calls the `onClose` method of the catalog.
Ideally, the client should not be closed when renaming the catalog.
However, to avoid extra checks in the `removeCatalog` method, we can simply execute `onRefresh`
in the `addCatalog` method to address this issue.
Following #25138, unified schema change interface for parquet and orc reader, and can be applied to other format readers as well.
Unified schema change interface for all format readers:
- First, read the data according to the column type of the file into source column;
- Second, convert source column to the destination column with type planned by FE.
