Make compression ratio for cached artifacts configurable

[lptr]

We could trade I/O for CPU (or vice versa) by decreasing (or increasing) the compression ratio of the cached artifacts. We could for example let local builds run with a faster compression, while CI builds could spend a bit more time compressing their outputs so that the created artifacts end up being smaller (and faster to download).

This could work with the existing Zlib compression, but it would probably have a higher impact if we introduced Zstandard compression (see #12809).
