  Samples: Add command line flag to select renderer.
  
  This gives us the ability to test Vulkan without a special recompile,
  and keeps the default setting to the default ANGLE renderer. Only
  implemented for the hello_triangle sample currently.
  
  Also includes an extra error message for missing EGL config, which is
  where the Vulkan init fails right now, due to missing depth/stencil
  support.
  
  Also includes a hack to get Vulkan samples running without depth/
  stencil.
