Add a selftest for SGX. It is a trivial test where a simple enclave copies one 64-bit word of memory between two memory locations.

Greg, speaking of dual licensing, I'd make an expection with this selftest to what we agreed in the last week.
It's the only compact C-only example that I'm aware of that shows how to put together the basics of an SGX user space. Here a more permissive licensing would make sense in my opinion just to give a seed for alternatives.
Right now the user space implementations are either in C++ and Rust, and they work great for big things like containers etc. I could envision someone to have something more minimalistic to do something simple for lets say a system daemon.
I've done a similar decision with tools/testing/selftests/tpm2/tpm2.py in the past.
What do you think?
