    build: various fixes to the InnoSetup scripts for CI.
    
    In the bat file:
    
    - Detect InnoSetup's path in the registry as we do in GIMP's CI.
    - fix Windows syntax: not sure why but various commands don't seem to
      work anymore. Or maybe these were for another shell syntax?
    - Don't use the START command: apparently it's to run in
      parallel/background commands. While it seems interesting for faster
      builds, it also requires for the CI to be able to wait for all scripts
      to finish and I don't see how to do this in this command's manual (+ I
      don't want to spend too much time searching as I cannot even test
      locally!).
    
    In the iss file:
    
    - Disable "Signed uninstaller mode".
    - rename the output file to avoid duplicate major version.
    - Use autopf instead of pf to fix:
    
    > Warning: Constant "pf" has been renamed. Use "commonpf" instead or consider using its "auto" form.
    
    - Remove WizardImageBackColor to fix:
    
    > Warning: The [Setup] section directive "WizardImageBackColor" is obsolete and ignored in this version 
of Inno Setup.
    
    - Add all the languages directly, like we do for GIMP's installer
      because InnoSetup don't seem to see the LANGUAGE inside an #if macro,
      cf. errors when running the .iss with iscc.exe:
    
    > Undeclared identifier: LANGUAGE.
    
      Note that currently all languages use the help.en.isl, which obviously
      makes no sense, but it will be fixed when we'll generate localized
      versions as we did for GIMP installer.
    
    - Source dir replaced by new HELPDIR macro set by the build.bat script.
    
    (cherry picked from commit 1f09e1f5c0fb1aef7ba781ad03b1520049b09edf)
