contrib: add a script to build all of the wheels on macOS

This is mostly a translation of `contrib/packaging/build-windows-wheels.bat`,
except the default pythons to build can be inferred from `setup.py` and/or
`pyproject.toml`, and all use the same configuration.  All we need to do is
force the building of translation files, tell it to skip pypy wheels, and tell
it to build universal2 wheels instead of for the current architecture.

"""
List-valued configuration keys have an ad-hoc microsyntax. From `hg help config`:

> List values are separated by whitespace or comma, except when values are
> placed in double quotation marks:
>
>     allow_read = "John Doe, PhD", brian, betty
>
> Quotation marks can be escaped by prefixing them with a backslash. Only
> quotation marks at the beginning of a word is counted as a quotation
> (e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).

That help documentation is fairly light on details, the actual parser has many
other edge cases. This test tries to cover them.
