Check supported features and properties for transform feedback tests

Builtin tests using shaderClipDistance and/or shaderCullDistance should
check if the features they need are supported. BackwardDependency test
should check if transformFeedbackDraw is supported.

Affects:
- dEQP-VK.transform_feedback.simple.xfb_clipdistance_*
- dEQP-VK.transform_feedback.simple.xfb_culldistance_*
- dEQP-VK.transform_feedback.simple.xfb_clip_and_cull_*
- dEQP-VK.transform_feedback.simple.backward_dependency

Components: Vulkan

VK-GL-CTS issue: 1934
