  Vulkan: Store VkDevice in vk::SharedPtr
  
  So that we don't need to have two versions of destroy() APIs. In
  previous CLs I had to add another version of destroy() that does not
  take device argument due to SharedPtr may calls destroy when last
  reference count goes away. Because we do not have device information at
  that time, destroy() API was added but mostly just doing assertion that
  Vulkan object has been explicitly destroyed. With this CL, we now stores
  device in the SharedPtr so that we no longer need two destroy() APIs.
  The explicit destroy(device) call will be removed in the next CL.
