Stores the enabled instance and device extensions during vkCreateInstance and vkCreateDevice respectively. This fixes an issue where function pointers for functions of disabled extensions were returned during vkGetInstanceProcAddr/vkGetDeviceProcAddr. Adds functionality for adding extensions that belong to a subset of other extensions in util::extension_list. Adds function for checking if the proper surface extension has been enabled in each WSI backend.
