Cocoa: Add basic support for Vulkan via MoltenVK

Browse Source 
This adds basic support for MoltenVK, a Vulkan implementation on top of
Metal, on macOS 10.11 and later.  It looks for MoltenVK in the process
via RTLD_DEFAULT symbol lookup if _GLFW_VULKAN_STATIC is disabled.

glfwCreateWindowSurface now creates and sets a CAMetalLayer for the
window content view, which is required for MoltenVK to function.

You must help CMake find MoltenVK for the Vulkan test to be built.

Fixes #870.
