GLFW now checks for the libvulkan.1.dylib loader instead of what is now the ICD. This removes checking for libMoltenVK.dylib to avoid cryptic errors. This unfortunately also breaks compatibility with the standalone MoltenVK SDK. This also removes support for the static loader library as that is not present in the LunarG SDK. Related to #870.
