confidential guest support: Update documentation

Now that we've implemented a generic machine option for configuring various
confidential guest support mechanisms:
  1. Update docs/amd-memory-encryption.txt to reference this rather than
     the earlier SEV specific option
  2. Add a docs/confidential-guest-support.txt to cover the generalities of
     the confidential guest support scheme
