ClickHouse build check	Builds ClickHouse in various configurations for use in further steps. You have to fix the builds that fail.

Use these options and follow the general build process	⏳ pending
Fast test	Normally this is the first check that is ran for a PR. It builds ClickHouse and runs most of stateless functional tests, omitting some. If it fails, further checks are not started until it is fixed. Look at the report to see which tests fail, then reproduce the failure locally as described here	❌ failure

@SuzyWangIBMer what do you mean? I'm gonna try to use new analyzer in EXPLAIN SYNTAX query because it can be the simplest way to understand if syntax level optimizations were applied for ClickHouse users. But it's recommended to use EXPLAIN QUERY TREE for ClickHouse developers or advanced users.

#61059 this pr set allow_experimental_analyzer to false with "EXPLAIN SYNTAX", explain syntax does not reflect analyzer optimized query result.
