[Windows] Build youtube-dl.exe as 2 files (library and exe loader) [required for signing the executable]

[romaincointepas]

Follow-up to #10372.

In order to sign a py2exe executable on Windows with SignTools, the library and the exe loader have to be detached (there is no other way as far as I know).

This blog post explains this very well:
https://medium.com/@bjoernstiel/code-signing-py2exe-executables-a222c0d06d3f
(It seems that the only thing to do is pass the option zipfile = "app.lib", right now it is set to None).

This is mostly required when shipping youtube-dl with signed Electron/nw.js apps (when the packager signs the main executables and all other executables shipped with the app).

Just to clarify, there is no need for the official youtube-dl.exe to be signed, the best approach would be to release an additional build of youtube-dl for Windows that would be 2 files: the youtube-dl-loader.exe and youtube-dl.lib (or something similar)?

@yan12125 Thoughts?

You can build youtube-dl whichever way you like. Releasing additional builds for specific corner cases is not an option.

I guess using official Python binaries from https://www.python.org/ with https://yt-dl.org/downloads/latest/youtube-dl is enough. You can just run python.exe youtube-dl and use it like youtube-dl.exe.
