Open source Lua CoreLibs on GitHub

Currently, there is no official way for the community to upstream bug fixes to the SDK CoreLibs. It is a manual process involving copy / paste and having to restore changes when updating the SDK and then waiting and hoping.

I propose the CoreLibs live in a repo somewhere for the community to contribute to and the upstream be part of each SDK release.

This may also require that CoreLibs be separated from the SDK releases, but one could possibly distribute the CoreLibs through a Lua package manager and have that as a default configuration for Lua based projects. Or perhaps it is a function of PDC. I am not entirely sure what the mechanism would be.
