Silvan Mosberger fbbe972898 Parallel GH actions workflow for Nixpkgs eval
Motivated by ofborg struggling [1] and its evaluations taking too long,
inspired by Jörg's initial PR [2]
and Adam's previous attempt to parallelise Nixpkgs evaluation [3],
this PR contains initial work to relief ofborg from its evaluation duty
by using GitHub Actions to evaluate Nixpkgs.

For now this doesn't take care of all of what ofborg does, such as
requesting appropriate reviewers or labeling mass rebuilds, but this can
be follow-up work.
