Use a separate executable for dedicated server

The dedicated server still has directx dll imports which will cause issues with ReShade or 3DMigoto, or trying to load it on a headless machine with no directx installed. The imports have to be cleared to avoid issues. The most convenient approach is to do this with a separate exe rather then patching it in runtime.
