Subject: [PATCH] Build ARM64 Windows wheels

ARM64 Python is available since Python 3.11, so add specs for 3.11-3.13

Use actions/setup-python to avoid using the host Python (3.9 currently
on windows-2022) since the arm image doesn't have a native Python atm
(see https://github.com/actions/partner-runner-images/issues/85) and
cibuildwheel warns that it will require 3.11 with v3, so might as well
bump it for everything.

Also adds one arm64 build to the default matrix setup, since the separate
image makes it different enough to warrant testing on PRs imo.

Fixes #109
