Description

The wheel build task in dev/tasks/python-wheels/github.osx.arm64.yml uses a hodgepodge of random arch calls that currently work but do not have a rational justification.

Someone should take a deep look at these and rationalize them: normally, it should be enough to create each Python environment with the right architecture.

Also, do note that the self-hosted M1 runner actually runs in x86 mode by default, so it's necessary to issue arch -arm64 to select ARM64 mode.
