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 2 heads containing the same file, once as
a file, once as a link. Bundle was generated with:

# hg init t
# cd t
# echo a > a
# hg ci -qAm t0 -d '0 0'
# echo l > l
# hg ci -qAm t1 -d '1 0'
# hg up -C 0
# ln -s a l
# hg ci -qAm t2 -d '2 0'
# echo l2 > l2
# hg ci -qAm t3 -d '3 0'

  $ hg init t
  $ cd t
  $ hg -q unbundle "$TESTDIR/bundles/test-merge-symlinks.hg"
  $ hg up -C 3
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

Merge them and display *_ISLINK vars
merge heads

  $ hg merge --tool="\"$PYTHON\" ../echo.py"

Test working directory symlink bit calculation wrt copies,
especially on non-supporting systems.
