[PATCH 3/4] vulkan-1/tests: Add a test for destroying a command pool.

[Józef Kucia]

The Vulkan spec says:

  "When a pool is destroyed, all command buffers allocated from the pool
  are implicitly freed and become invalid. Command buffers allocated
  from a given pool do not need to be freed before destroying that
  command pool."
