refactor: integrate more probe-engine workflows (#204)

This diff is part of https://github.com/ooni/probe/issues/1335.

We are moving more probe-engine workflows to toplevel.

The general idea here is to migrate all possible workflows and to
delete the ones that we cannot use in this repo (if any).
