Switch over remaining repositories to GitHub Actions

[mrcnski]

1. Switch all repos from Travis to GHA. This should be done after we figure out how to run parts of workflows on a schedule. Then, we can mostly copy the configuration from safe-nd, as it is simple and should easily extend to other repos with slight modifications (e.g. Routing has their own clippy script which should be called).
2. Update readmes and the QA page to point to the latest master build for each repo.
