Remove large files from repo and history

[alexbjorling]

Hi @rozyczko , I looked around a bit more and couldn't help pointing this out :)

This repo contains windows executables and dll:s. If they actually need to be version controlled with the code then git-lfs is a nice tool. But otherwise they could be removed.

The files themselves take up space in the tree but they also clog the history. A fresh clone is 126 M. Filtering just the libs/ folder reduces it to 26 M.

git-filter-repo --path libs --invert-paths

Further analysis of the history shows remnants of other large and/or binary files (images, static web content, etc) which could be filtered similarly to reduce size but keep other git history intact.

Thanks @alexbjorling ! Yes, these windows-specific libs were necessary at some point but we modified the binary signing process and they aren't needed anymore.
They will be removed for the next release

The disk footprint on Windows for the installer changes from 900MB to 839MB.
Small but useful improvement.
