vkformat: add gst_vulkan_format_from_video_info_2()
The purpose of this function is to get more info about the mapped Vulkan format from the GStreamer format, since they can be multiple Vulkan formats for one GStreamer format. Also a Vulkan format may have certain usage and aspects that must be verified. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4351>
