Add support for Apple Silicon

Based on the feedback from @tmaestrini

• add support for architecture osx-arm64
• update setup scripts

[waldekmastykarz]

Unfortunately, the osx-arm64 doesn't work. After starting it stops immediately. As a workaround for now, we patched the setup script to install x64 version on arm64 macs (#540) which seems to be working just fine. In parallel, we'll investigate why the arm64 version isn't working.

It works for me when I build from source. Possible to add this back to the next release?

Correct, it's working when you build it on your own machine, but fails if you try to run bits built elsewhere (like on CI/CD). We suspect it has to do with code signing. We're in the process of setting it up and should have something in a few weeks. We'll share an update then. For now, you can use osx-x64 bits.
