Improve vcpkg usage experience

[gafferongames]

I have no idea how to do this, or time to do it, but I'd be happy to support anybody else doing this.

I think the only way is via PR to vcpkg repository. The current way is fine but mostly used with closed source libraries and a bit longer to setup. I created an issue microsoft/vcpkg#26485 maybe there is some other easier way that links to this repo.

This is huge! I use vcpkg for my projects, and I definitely agree, it's a lot harder to set up the current way. If you need any support, let me know!

If somebody wants to do this, please create a PR. I nuked the old vcpkg setup now that we don't depend on sodium and mbedtls so it should be much easier now. Thanks!
