tests: port test-doctest.py from core hg

We already have a doctest string for evolve.obshistory.cyclic(), but of course
it didn't actually run. Something like test-doctest.py is first needed to run
doctests via run-tests.py.

    # Logic in the revsets below:
    # 1. There is target topic on stable or compatibility branch: merge all
    # those commits, they are related to our work and need to pass tests on all
    # compatibility branches.
    # 2. There is no target topic: avoid any commits that have topic set, they
    # are definitely unrelated to what we're doing.
    # In other words, if you want to test certain commits, assign them all to
    # one topic and provide that topic as the first argument to this script.
