vulkan/instance: expose extension/layer choices
Extensions and layers can be enabled before calling gst_vulkan_instance_open() but after calling gst_vulkan_instance_fill_info(). Use the list of available extensions to better choose a default display implementation to use based on the available Vulkan extensions for surface output. Defaults are still the same.
