[FEA] Support parquet row group skipping in Polars physical engine

[beckernick]

Polars provides the ability to skip row groups to avoid reading unnecessary data. I believe we aren't currently taking advantage of this the backend, but we could be (discussed offline).

This will be done once we hook up the ast expressions in the parquet reader.

This currently works, but once we merge #16944 it will be disabled again since we don't support pushdown in the chunked Parquet reader. We will need to enable that again.
