Vulkan: Don't allow creation of ES3 contexts. Refactor RendererVk::getMaxSupportedESVersion to limit max supported versions similar to RendererGL. This allows dEQP-EGL.functional.robustness.reset_context.shaders.infinite_loop.* tests to pass but they are currently skipped due to TDR issues on some platforms. When we start to test on top of ES3 contexts, we will either have to supress some dEQP EGL tests or expose it some other mechanism.
