…ttrNamesOnly The attrNamesOnly feature is used by pkgs/top-level/release-attrpaths-superset.nix to return a superset of all attributes that might be built by Hydra. Before this change it would include all attribute paths to derivations that could be found recursively, ignoring the recurseForDerivations and recurseForRelease attributes that control Hydra's recursion. This had the effect that it would end up with ~266000 attributes, most of which definitely won't be built by Hydra. We can remove those while staying true to the superset notion to end up with just ~97000, a reduction of ~63.6%! This also comes with an eval time reduction from 31.7s to 18.7s (-41.0%)! As an example, all derivations in pypy310Packages don't get included anymore, because it doesn't have a `.recurseForDerivations` set. As a nice side effect, with `--arg enableWarnings false`, no more warnings are printed, because things like `checkpointBuildTools.mkCheckpointedBuild` (which is deprecated) isn't being recursed to anymore. (cherry picked from commit 72f462b)
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.

This should now also contain the follow up fixes otherwise it's misleading as it tests the wrong commit. |

Although matrix.system is supposed to be generated from trusted code, we'd better follow [Github Actions good practices][1].

- `env.mergedSha` is empty, so it checked out the master version by default - The process step used `needs.attrs.outputs.mergedSha`, but apparently that's empty unless `attrs` is declared as a `needs`, even though `outputs` implicitly depends on `attrs` (cherry picked from commit 19db54e)
