Refactor how GetPhysDevFeats2 works

Browse Source 
Cleaned up the logic for handling when to use the core, the KHR, and when
not to use vkGetPhysicalDeviceFeatures2. This should make the logic easier
to follow with better names, and handle a few cases that were wrong, like
not caring if the extension is enabled by vulkan 1.1 is not.
