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).

How to add fuzzers (partially cribbed from oss-fuzz[0]):

  1) git clone https://github.com/google/oss-fuzz
  2) cd oss-fuzz
  3) python infra/helper.py build_image mercurial
  4) docker run --cap-add=SYS_PTRACE -it -v $HG_REPO_PATH:/hg-new \
         gcr.io/oss-fuzz/mercurial bash
  5) cd /src
  6) rm -r mercurial
  7) ln -s /hg-new mercurial
  8) cd mercurial
  9) compile
  10) ls $OUT

Step 9 is literally running the command "compile", which is part of
the docker container. Once you have that working, you can build the
fuzzers like this (in the oss-fuzz repo):

python infra/helper.py build_fuzzers --sanitizer address mercurial $HG_REPO_PATH

(you can also say "memory", "undefined" or "coverage" for
sanitizer). Then run the built fuzzers like this:

python infra/helper.py run_fuzzer mercurial -- $FUZZER
