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.

automation: support building Windows wheels for Python 3.7 and 3.8
The time has come to support Python 3 on Windows.
Let's teach our automation code to produce Windows wheels for
Python 3.7 and 3.8.
We could theoretically support 3.5 and 3.6. But I don't think
it is worth it. People on Windows generally use the Mercurial
installers, not wheels. And I'd prefer we limit variability
and not have to worry about supporting earlier Python versions
if it can be helped.
As part of this, we change the invocation of pip to `python.exe -m pip`,
as this is what is being recommended in Python docs these days. And
it seemed to be required to avoid a weird build error. Why, I'm not
sure. But it looks like pip was having trouble finding a Visual Studio
files when invoked as `pip.exe` but not when using `python.exe -m pip`.
Who knows.

packaging: support building WiX installers with PyOxidizer
We initially implemented PyOxidizer support for Inno installers.
That did most of the heavy work of integrating PyOxidizer into
the packaging system. Implementing WiX installer support was
pretty straightforward.
Aspects of this patch look very similar to Inno's.
The main difference is the handling of the Visual C++
Redistributable Runtime files.
The WiX installer was formerly using merge modules to
install the VC++ 9.0 runtime because this feature is
supported by the WiX installer (it isn't easily available
to Inno installers).
Our strategy for the runtime files is to install the
vcruntime140.dll file next to hg.exe just like any other
file. While we could leverage WiX's functionality for invoking
a VCRedist installer, I don't want to deal with the complexity
at this juncture. So, we let run_pyoxidizer() copy vcruntime140.dll
into the staging directory (like it does for Inno) and our
dynamic WiX XML generator picks it up as a regular file and
installs it.
We did, however, have to teach mercurial.wxs how to conditionally
use the merge modules. But this was rather straightforward.
Comparing the file layout of the WiX installers before and
after:
* Various lib/*.{pyd, dll} files no longer exist
* python27.dll was replaced by python37.dll
* vcruntime140.dll was added
All these changes are expected due to the transition to
Python 3 and to PyOxidizer, which embeded the .pyd and .dll files
in hg.exe.

packaging: move version derivation to run_wix_packaging()
With the previous commit moving signing inline, we no
longer need to compute the version string in build_installer()
and can instead move this logic to run_wix_packaging(). This
makes the logic in build_installer() simpler, which makes it
easier to implement alternate building mechanisms.

packaging: integrate signing into run_wix_packaging()
Previously, signing was implemented via a separate function
which called build_installer() and then called signing
functionality.
In this model, in order to implement an alternative build
mechanism, we would have to invent a new variant to handle
signing as well.
This commit merges the signing logic into the function invoking
wix. If we pass an argument holding metadata about how to sign,
we sign hg.exe and the installer. This means all we have to
do is pass in signing info and the signing just works.
A slight change here is that signing of hg.exe happens in the
staging directory as opposed to before the staging directory
is populated. I don't think this matters.

packaging: isolate invocation of WiX to own function
Like we did for Inno, we want to split out the building
of Mercurial from invoking the packaging tool so that we
can introduce an alternate build mechanism.
As part of this refactor, there are inconsequential changes
to file layouts. Before, some shared files such as the
WiX binaries and merge modules would be installed under
build/. Now, they are installed under build/wix-*. This
is to keep implementation simpler. But it also helps keep
build state more isolated.

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.

packaging: split Inno installer building from Mercurial building
We want to make the logic for producing the installer agnostic about
how Mercurial is built to allow for alternate build methods (like
PyOxidizer).

contrib: install PyOxidizer in Linux and Windows environments
For Linux, this was trivial.
For Windows, we need to teach the powershell script to install
Rust as well. This was also pretty straightforward.
