CAVP: DRBG proto messages

Background:
Need proto messages, this time for DRBG

New Stuff:
* Send and receive messages.
* Big send mesage, but it is likely that each is only 32 bytes long.

Notes/Caveats:
* This skips the EntropyReseed and AdditionalInputReseed fields

Bug: 156130023
Test: bazel run cavptests
