Disable query-level Groovy function by default

[npawar]

In Pinot you can write a Groovy script as part of your query: https://docs.pinot.apache.org/users/user-guide-query/scalar-functions#groovy-scripts. This is a security risk, and we should disable this by default. cc @mayankshriv

We had some discussion on this earlier too: https://github.com/apache/pinot/issues/7310. I would agree that groovy functions should be disabled by default :-)
