Merge branch 'synchronization-tests-fixes' into 'vulkan-cts-1.0-dev'

Various fixes for synchronization tests

- Tests were not querying the available queueCount in the queue family properties.
- Tests were using the "universal" queue family index when the device created in createTestDevice() could be using queues belonging to a different family index.
- 3D image view was being used with a 2D image.
- Command buffer Deleter was not holding any reference to the command pool.

- Fences tests:
    * Fence status VK_NOT_READY was expected between queueSubmit() and waitForFences(). Status could be VK_SUCCESS if the work finishes before waitForFences().
    * It seems that the first waitForFences() was intended for multiple fences, but it was waiting for one of the fences only.
    * Added check for default status of fence 1 (unsignaled).

- Code style:
    * DE_NULL was being used as a boolean parameter in createFences()
    * Use VkResult names instead of error codes in the error messages.
    * Fixed some typos and indentation.
