Fix strange python launcher error when folder has spaces

[HeDo88TH]

This PR fixes the behavior of innosetup to use the windows short path when it contains spaces.
The issue seems to be related to pypa/setuptools#216 and several others. I tested the same exact setup with newer python versions and they work fine. Unfortunately we are stuck with python 3.8 due to breaking changes in newer versions.

Bonus: added vcpkg, venv, python38, dist and innosetup folders to gitignore.

Closes #1569

Thanks. I'm a bit hesitant to accept this as a solution, it's my understanding that you're simply forcing users to install ODM to a path without spaces (via shortpath)? I also have concerns about that "Delete Folder" statement (potentially dangerous) and the ASCII encoding requirement (will this even work with non-ASCII characters in the path?)

If this issue was fixed in newer versions of Python, can't we just backport the patch?

For example, have you attempted to apply pypa/setuptools#2697 ?

We abandoned the short path workaround in favour of merging the folders python38 and venv\Scripts.
It works and test pipeline runs!

Need to wait for https://gitlab.com/gitlab-org/gitlab/-/issues/402616 to test this (it's causing the ODM builds to fail).

They messed up some hashes 😢

Everything checks out, thanks!
