Add upb test runs

This change adds test runs for GCC, Windows, and Mac. The 32-bit ASAN test
turned out to be somewhat difficult to migrate, so I left a TODO for that one.

I made sure to give each build environment its own cache prefix, so that we
don't end up with artifacts built by different toolchains conflicting with each
other in the same cache.
