Wheels not available for MacOS ARM python 3.8 / 3.9

[AdamGlustein]

The current build process uses macos-14 native arm runner to build our arm wheels: https://github.com/Point72/csp/blob/063b137f61867cf391b97abf31031d4621844e3b/.github/workflows/build.yml#L223

That limits the build to only python 3.8/3.9. Instead, we can remove the macos-14 arm runners and cross compile from x86 runners https://github.com/Point72/csp/blob/063b137f61867cf391b97abf31031d4621844e3b/.github/workflows/build.yml#L291
