vulkan: Add a concept of recycling an object

Browse Source 
This is not necessarily a full re-initialization of the object but is
whatever is necessary/expedient for the client to see it as a new object
and not the one it has seen before.  For vk_base_object, this removes
any private data and resets the object name to NULL.
