[Library] Update zlibng (#1255)

Browse Source 
* Update zlibng

* Set cmake path more directly in zlibng to hopefully fix an issue with the build on drone

* I'm dumb, missing / in path

* Mackal helps with a dumb gitignore issue

* Adding all the files, not sure what's ignoring them and im tired of looking

* Some tweaks to zlibng build to hopefully get it to build properly. works on msvc now
