Update SQLancer Source Code for NoisePage

[apavlo]

@jazzplato is leading the effort to port SQLancer to our system. We are going to start with the DuckDB implementation and then remove the SQL features that we don't support yet (e.g., some SQL functions).

We have a breakdown of the files that we need to port:

Our fork of SQLancer is here: https://github.com/cmu-db/sqlancer

I will assign one file to each team member. The main idea is we should comment out (i.e., do not remove) any SQL feature that we do not support. You should then send your patch to @jazzplato who will then merge them into our fork.
