版本1.2.8 执行 SQL 语句带有 fulltext 语法 `MATCH (col1,col2,...) AGAINST (expr [search_modifier])` 时报错

语句能正常执行并返回结果，但是 Druid 报 ParserException

```

Reproduce the reported MATCH ... AGAINST statement through StatFilter.mergeSql and inspect SQLStatementParser.parseStatementList and ParameterizedOutputVisitorUtils.parameterize, which appear in the stack trace. Add a regression test for the fulltext syntax and verify that SQL parsing and parameterization complete without ParserException while preserving the query result.
