Remove SSE detection duplication in Colors and ModelRenderer

Browse Source 
- Rename macros to be more explicit
 - Move detection code to a separate file
 - Remove a lot of checks in ARB mode (ModelDef.cpp would check for sse
multiple times per frame)
 - Make explicit the SSE2 dependency for Windows
