Support for aarch64-apple-darwin?

[repi]

With the new ARM-powered Mac's coming out next week it would be very nice with support for building this crate for the new aarch64-apple-darwin target, so filing this as a tracking issue towards it but understand it likely would be quite a bit of build system work to do and may need some upstream dependency fixes and support as well.

Since a month ago it is possible to build towards it with nightly with cargo +nightly build --target aarch64-apple-darwin but looks like one runs into build errors with crashpad with it right now

Sorry for my long absence!

Apparently this is already being worked on: getsentry/sentry-native#445.
I would also love to some CI: actions/runner-images#2187.

So this has been fixed upstream now and should work. Sadly I can't even test the build in CI because of actions/runner-images#2486.

Feel free to re-open if any issues arise.

Apparently there is an issue with static zlib compilation, see getsentry/sentry-native#486.
I've already made a PR: getsentry/crashpad#34, #29.
