feat: add cli-32 and cli-64 from conda project

[wolfv]

I think we should still document more where these come from. I'll try to find more info from @jezdez and co.

I would also like to find out if the 64 bit executable works on Windows ARM64 ... it might?!

Those launchers are copied from conda-build.

This was just an observation or something actionable? :)

Unfortunately, the knowledge on how to build these launchers seems to have been "lost" :D

I had high hopes that Anaconda could build the win-arm64 launcher (cc @jezdez).

@wolfv this is a good idea IMO, for the https://github.com/conda-incubator/installer team, I'm tapping @marcoesters and @Callek to help move the building of the binaries into an own repo, so we can start using them and build them correctly for new platforms

Mentioning it because the README in this PR says the source is conda/conda, but the actual source is conda/conda-build. That directory contains the source files and build scripts, which have some comments too. I think it's a matter of running the build scripts with some compilers assumed to be present.
