[ci] Script for building M1 wheels (#19925)
[ci] Script for building M1 wheels (#19925)


This PR includes a script for building wheels for Macs with M1 processors. It roughly follows the pattern of the other scripts with a few differences.

Manually installs nvm
Uses miniforge conda to install python/pip instead of python foundation .pkgs
Doesn't pin numpy (we probably shouldn't be pinning it in the other scripts either...)
Commit detection falls back to git instead of erroring
All of these changes were made so that the script works on a laptop, which comes with a subset of the dependencies that the x86 buildkite image comes with.
