CAVP: Add AES-GCM proto messages

Background:
We need a message that we can use to communicate info about GCM

New Stuff:
* GCM Test and TestResult messages for doing encrypt/decrypt
  simulultaneously.

Notes/Caveats:
* There is also a AesGcmEncrypt message already there, but it doesn't
  let us do decryption, so I'm ditching it.

Bug: 156128617
Test: bazel run cavptests
