vintagestory: add support for experimental .net 7 build

Future versions (1.19+) will be built exclusively on .net 7, see: https://www.vintagestory.at/blog.html/news/v1186-stable-security-patch-r360/ and https://www.vintagestory.at/blog.html/news/v1186-rc2-hunting-the-performance-leak-r359/
This change crates the foundations for suporting .net 7 going forward and adds an override option to enable the experimental .net 7 build
