  Reland: vulkan: add EGL_ANGLE_platform_angle_vulkan_device_uuid
  
  Implement the ability to select a specific device and driver combination
  through a few new selection criteria:
  
      VkPhysicalDeviceIDProperties::deviceUUID
      VkPhysicalDeviceIDProperties::driverUUID
      VkPhysicalDeviceDriverProperties::driverID
  
  Earlier version had problems due to a test build issue. Per syoussefi@,
  going to rework the test into a separate CL so that we get the core
  change merged.
