Make sure vkGetDescriptorSetLayoutSupport limits are tested

The dEQP-VK.api.maintenance3_check.descriptor_set test tried several
descriptor set types and count combinations and checked if they falled
within acceptable limits. If they did not, no check was performed for
that combination. The test may have ended up passing with no check being
done because of that.

This commit makes the test combinatorial in nature and adds support for
inline uniform blocks in reasonable cases.

Affected tests:
dEQP-VK.api.maintenance3_check.descriptor_set

Components: Vulkan
VK-GL-CTS issue: 1879
