Review Comment:
This will cause the simple SQL to fail in Trino like `select * from xx`.
The latest Trino code adds a configuration to enable compatibility with REST
server that does not support view operations. But for the old trino releases,
it couldn't work with Gravitino. This PR moves the compatibility work from
client to server, I agree that this is a workaround solution, is more general
solution is https://github.com/apache/gravitino/issues/6395 but it benefits the
cooperation with Trino and Gravitino IRS.
