packaging: add -python2 to Windows installer filenames

We just taught the Windows installers to produce Python 3 variants
built with PyOxidizer.

Our plan is to publish both Python 2 and Python 3 versions of the
installers for Mercurial 5.4.

This commit teaches the Inno and WiX installers to add an optional
string suffix to the installer name. On Python 2, that suffix is
"-python2." We reserve the existing name for the Python 3 installers,
which we want to make the default.

Create a DAG where a changeset reuses a revision from a file first used in an
extinct changeset.

Adding a changeset going extinct locally
------------------------------------------

Pull a changeset that will immediatly goes extinct (because you already have a
marker to obsolete him)
(test resolution of issue3788)

  $ hg phase --draft --force f89bcc95eba5
  $ hg phase -R ../other --draft --force f89bcc95eba5

check that bundle is not affected

  $ hg bundle --hidden --rev f89bcc95eba5 --base "f89bcc95eba5^" ../f89bcc95eba5.hg
