vkGetPhysicalDeviceFeatures2 and vkGetPhysicalDeviceProperties2 are not present on some MoltenVK versions.
VK_KHR_get_physical_device_properties2 exposes the KHR versions of the same functions.
These cannot be used via static linking, so we have to dynamically detect the loader version and then the extension
to work out which pointers to use.

MoltenVK, at least upto 1.2.141, does not render triangle fans. This is reflected in the portability EXTX extension.
This code get the extensions properties and features and then sets the have_triangle_fans.
This extension is not avaiable on all systems, so an amout of the code has to be protected by the define VK_EXTX_PORTABILITY_SUBSET_EXTENSION_NAME.

Extends the flexability of the device info script.
Allows #if defined()/#endif guards around particular data, for platform or version specific structures.
Allows for feature structures to be retreved without having to have a have_ variable as well. Helps if there is more than one feature in the structure.
These changes help towards allowing the use of the portability set extensions.
