SGXv2 platforms support calling the rdtscp instruction inside an enclave. This PR implements logic to keep track of the time inside of an enclave. Note that the value rdtscp returns, can be manipulated by an attacker; even with these changes insecure_time is (almost) as insecure as before. There's only an option to force the time to be monotonic.
This PR is one of the parts of #648 that was split up.
