Message : 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.
