lib/crypto: tests: Add KUnit test suite for AES-CCM

Browse source

Add a KUnit test suite for the AES-CCM library API.

It consists of:

- All the shared test cases from aead-test-template.h.  These include
  extensive consistency tests, a "Monte-Carlo test", and a benchmark.

- Tests against hardcoded AES-CCM test vectors from external sources.

- Tests for CCM-specific message length validation.

To generate the expected aes_ccm_monte_carlo_checksum[] value, add a
script gen-aead-testvecs.py which computes it using python-cryptography.
