Test contradictory parameters on swapchain creation

Test contradictory parameters on swapchain creation

This commit adds new tests that check the implementation properly
ignores queueFamilyIndexCount and pQueueFamilyIndices on swapchain
creation when imageSharingMode is set to VK_SHARING_MODE_EXCLUSIVE, by
providing a null pointer in pQueueFamilyIndices and a nonzero
queueFamilyIndexCount.

In addition, swapchain creation tests using VK_SHARING_MODE_EXCLUSIVE
will no longer pass 1 in queueFamilyIndexCount and a list of
surface-compatible queues in pQueueFamilyIndices, setting
queueFamilyIndexCount to 0 and passing a null pointer instead.

Finally, the commit adds de::arrayLength as a more modern and constexpr
way of obtaining the size of statically-sized arrays, similar to
DE_LENGTH_OF_ARRAY, which can be used with static_assert.

New tests:
dEQP-VK.*exclusive_nonzero_queues

Affected tests:
dEQP-VK.*.swapchain.create.*

Components: Framework, Vulkan
VK-GL-CTS issue: 3244
