crypto: ccp - Add unit tests for dynamic boost control

Interacting with dynamic boost control messages requires the caller
to supply a signature. To allow validation of individual dynamic
boost control components, introduce a set of tests that can be run.

The tests can be run in 3 distinct different environments, and so
certain tests will be skipped depending on the environment.

1. Systems that do not support DBC.
2. Production systems that support DBC but are secured silicon.
3. Pre-production systems that support DBC but are unsecured silicon.

Unsecured silicon does not validate the signature, and so this allows
testing more of the state machine and functionality.
