gitlab-ci, build: construct the Windows installer from CI.

Run InnoSetup in the Windows CI to build the installer from both the 32
and 64-bit builds.

Current limitations:
- No installer signature yet.
- Dependencies will have to be checked more thoroughly.
- Apart from babl and GEGL, we may want to make custom builds of any
  package which has a patch in build/windows/patches/ (Windows-specific
  patches) and build/patches/ (all platform patches).
- Plug-in interpreters (Python, Lua…) don't work. This will need to be
  looked at in detail.

Globally this first automated installer build works fine though, as I
could install it in a Windows 10 VM and GIMP ran fine! So it's a first
step towards fully automated releases for Windows.
