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.

  $ hg init repo
  $ cd repo

add or rename files on top of the master branch

  $ echo a1 > a
  $ echo b1 > b
  $ hg commit -qAm 1
  $ hg bookmark -i main
  $ hg fastannotate --debug -nf b
  fastannotate: b: 1 new changesets in the main branch
  0 b: b1
  $ hg fastannotate --debug -nf a
  fastannotate: a: 1 new changesets in the main branch
  0 a: a1
  $ echo a2 >> a
  $ cat > b << EOF
  > b0
  > b1
  > EOF
  $ hg mv a t
  $ hg mv b a
  $ hg mv t b
  $ hg commit -m 'swap names'

existing linelogs are not helpful with such renames in side branches

  $ hg fastannotate --debug -nf a
  fastannotate: a: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  $ hg fastannotate --debug -nf b
  fastannotate: b: linelog cannot help in annotating this revision
  0 a: a1
  1 b: a2

move main branch forward, rebuild should happen

  $ hg bookmark -i main -r . -q
  $ hg fastannotate --debug -nf b
  fastannotate: b: cache broken and deleted
  fastannotate: b: 2 new changesets in the main branch
  0 a: a1
  1 b: a2
  $ hg fastannotate --debug -nf b
  fastannotate: b: using fast path (resolved fctx: True)
  0 a: a1
  1 b: a2

for rev 0, the existing linelog is still useful for a, but not for b

  $ hg fastannotate --debug -nf a -r 0
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  $ hg fastannotate --debug -nf b -r 0
  fastannotate: b: linelog cannot help in annotating this revision
  0 b: b1

a rebuild can also be triggered if "the main branch last time" mismatches

  $ echo a3 >> a
  $ hg commit -m a3
  $ cat >> b << EOF
  > b3
  > b4
  > EOF
  $ hg commit -m b4
  $ hg bookmark -i main -q
  $ hg fastannotate --debug -nf a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 3 new changesets in the main branch
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a
  fastannotate: a: using fast path (resolved fctx: True)
  1 a: b0
  0 b: b1
  2 a: a3

linelog can be updated without being helpful

  $ hg mv a t
  $ hg mv b a
  $ hg mv t b
  $ hg commit -m 'swap names again'
  $ hg fastannotate --debug -nf b
  fastannotate: b: 1 new changesets in the main branch
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf b
  fastannotate: b: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  2 a: a3

move main branch forward again, rebuilds are one-time

  $ hg bookmark -i main -q
  $ hg fastannotate --debug -nf a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 4 new changesets in the main branch
  0 a: a1
  1 b: a2
  3 b: b3
  3 b: b4
  $ hg fastannotate --debug -nf b
  fastannotate: b: cache broken and deleted
  fastannotate: b: 4 new changesets in the main branch
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  1 b: a2
  3 b: b3
  3 b: b4
  $ hg fastannotate --debug -nf b
  fastannotate: b: using fast path (resolved fctx: True)
  1 a: b0
  0 b: b1
  2 a: a3

list changeset hashes to improve readability

  $ hg log -T '{rev}:{node}\n'
  4:980e1ab8c516350172928fba95b49ede3b643dca
  3:14e123fedad9f491f5dde0beca2a767625a0a93a

annotate a revision not in the linelog. linelog cannot be used, but does not get rebuilt either

  $ hg fastannotate --debug -nf a -r 96495c41e4c12218766f78cdf244e768d7718b0f
  fastannotate: a: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a -r 2
  fastannotate: a: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a -r .
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  1 b: a2
  3 b: b3
  3 b: b4

annotate an ancient revision where the path matches. linelog can be used

  $ hg fastannotate --debug -nf a -r 0
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  $ hg fastannotate --debug -nf a -r 653e95416ebb5dbcc25bbc7f75568c9e01f7bd2f
  fastannotate: a: using fast path (resolved fctx: False)
  0 a: a1
