Fall 2024 recompile of the natives (#1416)

This time around, instead of the very ad hoc approach I have historically taken, this time we actually have a convenient script that takes care of basically all the hard work necessary, including cross-compilation.

We compile natives for Ubuntu 20.04 LTS (OpenSSL 1.1.x native and libdeflate) and Ubuntu 22.04 LTS (OpenSSL 3.x.x native), for both x86_64 and aarch64.

The macOS natives have also been recompiled on macOS Sonoma.
