tests: Add `--rhg` and `--with-rhg=<path>` options for `run-tests.py`

They are mostly equivalent to the corresponding `chg` options.
For now, many tests are still failing in this configuration.
It is *not* run on CI.

Differential Revision: https://phab.mercurial-scm.org/D10095

Test extension of unfinished states support.
