Remove saving a function pointer only used once

Browse Source 
This removes the global struct member for
vkEnumerateInstanceExtensionProperties, which is only used in the same
function that fetches the function from the loader.

The pattern is now more in line with how other single uses of Vulkan
functions are structures, such as window surface creation.
