The functions are now defined under their core names. To avoid code bloat, I've defined the suffixed names as aliases of the core names. Both symbols will be globally defined with the same value, and in the dylib both will be exported. Fix the default API version when none is given. Zero is the same as `VK_API_VERSION_1_0`. Prior to this, we were overwriting it with zero if no app info were given, or if it were zero in the app info. It wasn't important before, but now that we gate API availability on maximum Vulkan version, we need to make sure it's a valid version.
