packaging: support building Inno installer with PyOxidizer

We want to start distributing Mercurial on Python 3 on
Windows. PyOxidizer will be our vehicle for achieving that.

This commit implements basic support for producing Inno
installers using PyOxidizer.

While it is an eventual goal of PyOxidizer to produce
installers, those features aren't yet implemented. So our
strategy for producing Mercurial installers is similar to
what we've been doing with py2exe: invoke a build system to
produce files then stage those files into a directory so they
can be turned into an installer.

We had to make significant alterations to the pyoxidizer.bzl
config file to get it to produce the files that we desire for
a Windows install. This meant differentiating the build targets
so we can target Windows specifically.

We've added a new module to hgpackaging to deal with interacting
with PyOxidizer. It is similar to pyexe: we invoke a build process
then copy files to a staging directory. Ideally these extra
files would be defined in pyoxidizer.bzl. But I don't think it
is worth doing at this time, as PyOxidizer's config files are
lacking some features to make this turnkey.

The rest of the change is introducing a variant of the
Inno installer code that invokes PyOxidizer instead of
py2exe.

Comparing the Python 2.7 based Inno installers with this
one, the following changes were observed:

* No lib/*.{pyd, dll} files
* No Microsoft.VC90.CRT.manifest
* No msvc{m,p,r}90.dll files
* python27.dll replaced with python37.dll
* Add vcruntime140.dll file

The disappearance of the .pyd and .dll files is acceptable, as
PyOxidizer has embedded these in hg.exe and loads them from
memory.

The disappearance of the *90* files is acceptable because those
provide the Visual C++ 9 runtime, as required by Python 2.7.
Similarly, the appearance of vcruntime140.dll is a requirement
of Python 3.7.

Check out of sync nodemap
=========================

First copy old data on the side.

  $ mkdir ../tmp-copies
  $ cp .hg/store/00changelog-????????????????.nd .hg/store/00changelog.n ../tmp-copies

Nodemap lagging behind
----------------------

make a new commit

  $ echo bar2 > bar
  $ hg ci -m 'bar2'
  $ NODE=`hg log -r tip -T '{node}\n'`
  $ hg log -r "$NODE" -T '{rev}\n'
  5003

If the nodemap is lagging behind, it can catch up fine

  $ hg debugnodemap --metadata
  uid: ???????????????? (glob)
  tip-rev: 5003

  $ hg log -r "$NODE" -T '{rev}\n'
  5003

changelog altered
-----------------

If the nodemap is not gated behind a requirements, an unaware client can alter
the repository so the revlog used to generate the nodemap is not longer
compatible with the persistent nodemap. We need to detect that.

  $ hg up "$NODE~5"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo bar > babar
  $ hg add babar
  $ hg ci -m 'babar'
  created new head
  $ OTHERNODE=`hg log -r tip -T '{node}\n'`
  $ hg log -r "$OTHERNODE" -T '{rev}\n'
  5004

  $ hg --config extensions.strip= strip --rev "$NODE~1" --no-backup

the nodemap should detect the changelog have been tampered with and recover.
