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.
