Includes a new GstVulkanHandlePool base class for pooling different resources togther. The descriptor cache object is ported to GstVulkanHandlePool with the exact same functionality. A new GstVulkanFenceCache is also implemented for caching fences which is used internally by GstVulkanDevice for creating or reusing fences. The existing GstVulkanTrashFenceList object now caches trash objects.
