Publish macOS arm64 build with GitHub releases

[Nezteb]

Currently Odin publishes builds for the following platforms:

• macos-amd64
• ubuntu-amd64
• windows-amd64

I'd also like to see a version for macos-arm64 so that macOS users with newer hardware don't have to compile Odin from source if they would prefer.

I assume the absence of arm64 builds is because GitHub Actions don't support hosted macOS arm64 runners (yet?). They do support self-hosted runners, but that would require someone on the core team to have a dedicated M1/M2 machine running it.

A simpler alternative would be to have someone with an M1/M2 manually build Odin and add it to the GitHub release whenever it is ready.

What do y'all think?

EDIT: "Apple Silicon (M1) powered macOS runners are now available in public beta"

I made a PR to add this here: #3163

While the GH runners are available for enterprise.. I don't know if it works for an open source project like this.

However.. buildjet is awesome, cheap and super easy to setup.

I'd be happy to donate the $10 required (if needed)

Github added mac/arm64 support a while ago, and Laytan's PR was merged. Closing out this discussion. Thanks for the offer, though.
