Update VulkanHeaders generator
- generate sType as with default value - add a script to generate all the headers we need along with function loading - use sized enums - fix bitwidth, don't load funcpointer - generate FeaturesConfigMap, FeaturesConfig and the loader for it - skip useless shit extension features
