build macos arm64 wheels

[luizirber]

Previous try (in #1334) tried to build universal2 wheels on mac, but that's complicated. This PR builds two separated wheels, one for arm64, another for x86_64, and let pip choose the correct one during installation.

I also updated cibuildwheel to list configuration in pyproject.toml, this way it can also be tested locally.

(In preparation for fixing the currently broken sourmash-minimal package on conda-forge, which is not doing the cross-compilation properly).
