Update wheel building workflow to include Python 3.11

[grlee77]

This was initially successful for all but win32/Python 3.10: https://github.com/grlee77/pywt/actions/runs/3028888975

Updating the pyproject.toml numpy pinnings for windows as in SciPy fixed the issue (non-windows cases were commented out in that commit): https://github.com/grlee77/pywt/runs/8287429816?check_suite_focus=true

Aside from adding Python 3.11 this MR

• removes all linux i686 builds
• splits the Windows and MacOS build matrix into parallel actions
• changed to using ubuntu-latest
• some updates to NumPy pinnings in pyproject.toml

Not sure if we should also drop the universal2 wheels on MacOS?

Yes please!

CI here didn't run the wheel builds, but assuming they were tested on your fork I think this is good to go modulo my one comment.

It had passed here. I cancelled some long running aarch64 cases that had passed in a previous test run.
