Add Mac aarch64 executable

[csasarak]

Overview

This adds an arm build of the CLI for Mac. You can get binaries from the build macOS-aarch64-build action below.

Acceptance criteria

A build that works on Mac M1.

Testing plan

I had set up an ARM EC2 instance, copied the binaries there and ran them. Additionally I ran a direct license-scan to verify that the license scan program worked correctly.

Risks

Costs will increase since we will be allocating two runners for Mac per build. Caching may become less reliable as we make more cache data as well.
