Clean up wsock proxy code and move wsock build system logic (#671)v1.24.1-rc2v1.24.1-rc1v1.24.1

- moves `WSockProxy` to `wsockproxy/CmakeLists`
- remove exepath stuff from dllmain
  + its still done in loader.cpp because its used when reporting failure
- Disabled any Thread Library calls
  + we don't need to know about threads at all in the proxy
- yoink `wsock32.asm` into outer space
  + turns out, we can just call the function in a void shim since that wont touch the registers
- stop copying `wsock32.dll` to the game directory
  + this should improve the state of things when using the EA App
