* ci: Add workflow to build against system 3rdparty

This is mostly about fmt/spdlog being a fast moving target breaking
source-compat as they go along.

Added homebrew only, which has the latest versions, so is enough
for good coverage.

Created separate .yml file as the main one is getting complex.

* Update .github/workflows/build-external.yml
