vulkan: Add a common implementation of VkFence
This is built on the new vk_sync primitives. In the vk_physical_device, the driver provides a null-terminated array of vk_sync_type pointers in priority order. The fence implementation then selects the first type that meets the necessary criterion. In particular, fences can't be timelines and need to support reset and CPU wait. It also auto-selects the fence type based on the external handle types provided and can down-grade as needed to support a particular external handle. The implementation itself is mostly copy+pasted from ANV. The primary difference is the fact that anv_fence_impl has been replaced with vk_sync. The permanent vk_sync is still embedded (like ANV) but the temporary one is a pointer. This makes stealing the temporary state as part of VkQueueSubmit a bit easier. All of the interesting stuff around waits, resets, etc. is implemented by the vk_sync interface. All this code does is wrap it all in the annoyingly detailed VkFence rules so we can provide the correct Vulkan entrypoint behavior.
