Is your feature request related to a problem? Please describe.

set sql_dialect = 'trino';
select json_extract(json, '$.store.book') --正常
select date_sub(current_date, interval 14 day) --正常
但是
select json_extract(json, '$.store.book') , date_sub(current_date, interval 14 day) -- 不正常
原因是 json_extract符合trino语法，date_sub(current_date, interval 14 day) 符合SR语法，所以两个单独查询没问题，但是联合查时会有异常，会带来困惑

Describe the solution you'd like

新增参数，支持配置是否允许从Trino降级到StarRocks方言
