Debug Trace

The Level Zero Loader has the ability to print warnings and errors which occur within the internals of the Level Zero Loader itself.

To enable this debug tracing feature, set the environment variable ZE_ENABLE_LOADER_DEBUG_TRACE=1.

This will enforce the Loader to print all errors whether fatal or non-fatal to stderr with the PREFIX ZE_LOADER_DEBUG_TRACE:.
