feat(sqlsmith): Support generate fuzz query sql

[b41sh]

I hereby agree to the terms of the CLA available at: https://docs.databend.com/dev/policies/cla/

Summary

Generate fuzz query based on a Statement, the Exprs in the previous Statement will be collected and randomly add to the new fuzzed Statement. This will create a lot of interesting combinations to find potential bugs.

This PR just implements the basic fuzz functionality, we still need to find some suitable seed SQL to execute.
