run-tests: introduce a --pyoxidized option

This options make it possible to use the pyoxidizer version to run the tests.
This is a first basic version that is windows only.

The test needs a working python, with Mercurial installed. However the
pyoxidizer product is "self contains" without a "usable" Python. There have been
discussion to have a fully functional `hg admin::python` command providing a
fully functional python interpreter, but nothing is of the sort is ready yet. In

In the meantime we use an hybrid approach, similar to what we do for testing
`rhg`. We install a full "normal" Mercurial, but also the pyxodizer product as
the official `hg binary`. That way, we use the pyoxidizer version or everything,
but test that needs to run python have it available, with a fully functional
Mercurial package.

This first version is pretty basic (Windows only, no --local, not
--with-pyoxidized), but it runs, various bug that we will have to fix.

Differential Revision: https://phab.mercurial-scm.org/D11277

https://bz.mercurial-scm.org/2137

Setup:

create a little extension that has 3 side-effects:
1) ensure changelog data is not inlined
2) make revlog to use lazyparser
3) test that repo.lookup() works
1 and 2 are preconditions for the bug; 3 is the bug.
