{cmake} Explicitly turn off ASM686 and AMD64 cmake options when ASSIMP_BUILD_ZLIB is on 

The AMD64 option causes a build failure on MSVC (#1760) and the ASM builds seem to have problems:

   https://github.com/madler/zlib/issues/41#issuecomment-125848075

This change also prevents these from "polluting" the cmake options if assimp is being included as a submodule.
