If the loader calls vkNegotiateLoaderLayerInterfaceVersion and it fails either due to the version being unsupported or the call returned an error code, skip the layer rather than trying to use a lower interface version.
Add error enums for when negotiation of the interface version fails and when the loader cannot load vkGetInstanceProcAddr.
vkEnumerateDeviceLayerProperties currently returns all layers that are in the app_activated_layer_list, regardless of whether they successfully loaded the binary or not. This change makes it so that only layers with the lib_status of 'success' and 'not loaded' (which corresponds to meta layers), will be enumerated
Also skip layers that failed to load while enumerating device extensions.
