Merge panic-abort and panic-log crates into mc-sgx-panic

[nick-mobilecoin]

This moves the previously named mc-sgx-panic crate to
mc-sgx-panic-sys.

Previously there was:

• mc-sgx-panic some common panic logic used by mc-sgx-sync for determining panic situations for lock aquisition logic. This was named vanilla panic as it was good enough at the time, but it still felt odd.
• mc-sgx-panic-abort was a panic handler that only called abort()
• mc-sgx-panic-log was a panic handler that would log and end in a spinloop

There was a desire to update the mc-sgx-panic-log to also abort(), or similar, it seemed that merging these 2 crates and providing a log feature would be a better path. It also seemed like mc-sgx-panic would be the crate that most clients would want to use. The mc-sgx-panic-sys name was chosen for the common panic backend logic as -sys is often used to indicate a system specific crate that clients shouldn't usually depend directly on.
