Which issue does this PR close?

• Closes Speedup execution of sqllogictests with more parallelization #20524

Rationale for this change

push_down_filter_regression.slt is the sqllogictest that takes the longest to run, even after @Tim-53 reduced its time in

• Improve sqllogicteset speed by creating only a single large file rather than 2 #20586

While reviewing #20586 and trying to make the sqllogictest runs faster, I noticed that a substantial amount of the unit test time was spent doing zstd compression/decompression:

Thus, we can improve the test speed by skipping the zstd step

What changes are included in this PR?

1. Don't compress the parquet files in the test

Are these changes tested?

Yes by CI
