Subject: [PATCH] .github/workflows/build_mpy_cross.yml: Build various
 mpy-cross binaries.

This provides binaries that will be used to generate mpy-cross binaries
for inclusion in a future PyPI package.

Includes Linux (32-bit and 64-bit), Windows (32-bit and 64-bit), aarch64
(e.g. 64-bit Raspberry Pi 4), armhf (e.g. earlier 32-bit Raspberry Pi),
macos (x64, works on M1/ARM too).

Currently using Ubuntu Bionic as the build environment (so that it supports
older glibc, i.e. Ubuntu Bionic LTS and Debian Buster). This is
deprecated, but we can move to Focal when support is removed (which will
support the current Debian/Raspbian Bullseye and Ubuntu LTS).

This work was funded through GitHub Sponsors.
