Fix segmentation fault in KQL parser when the input query exceeds the max_query_size (#59626)
* Fix_kql_issue_found_by_wingfuzz

This commit fix the issues:
 https://github.com/ClickHouse/ClickHouse/issues/59036
 https://github.com/ClickHouse/ClickHouse/issues/59037

both issues are same reason, the input query exceed the max_query_size,
so the condition isEnd() of token is not meet and cause the assertion failure

* fix_kql_issue_found_by_wingfuzz: use isValid instead of TokenType::EndOfStream

* fix_kql_issue_found_by_wingfuzz: make functional test result consist

* fix_kql_issue_found_by_wingfuzz: update test case for makeseries

* fix_kql_issue_found_by_wingfuzz: disable makeseries

* fix_kql_issue_found_by_wingfuzz:
 use isvalid() function to replace isEnd() function of TokenIterator to check the end of stream

* fix_kql_issue_found_by_wingfuzz: add test case for max_query_size

* fix_kql_issue_found_by_wingfuzz: fix AST structure

* fix_kql_issue_found_by_wingfuzz: make sure the max query size test is in the dialect of kusto

* fix_kql_issue_found_by_wingfuzz : restore max query size after test

* fix_kql_issue_found_by_wingfuzz : fix typo
