  Vulkan: Always query EGL_WIDTH and EGL_HEIGHT
  
  This fixes the failures of the dEQP EGL resize tests on Android.
  Those tests don't actually resize the window (which would allow the
  tests to pass), but do change internal Android Surface values that
  vkGetPhysicalDeviceSurfaceCapabilitiesKHR queries.  Therefore, by
  freshly querying these values the test passes.
