added test platform MacOS (#828)

* Just for a laugh, lets naively throw the same build at non linux OS

* Only run apt commands on linux (yes, this is not actually right, but it is close enough for github actions at the moment)

* Start installing required macOS packages

* Only run apt commands on linux #2

* Ensure that we use a Bourne shell, even on Windows

* Until it is clear how to install autotools on windows in github runners, avoid fighting that bear

* Only try to run gcovr on ubuntu-latest

* Install the right macos dep

* Install gcovr on macos and upload all coverage report artifacts

* Upload a generated tests output artifact, even if the tests failed

* Prepend a quick smoke test to the full matrix and coverage builds

* Use short names for jobs
