Move the ChaCha20Poly1305 test from an ad-hoc self-test to a KUnit test.
Keep the same test logic for now, just translated to KUnit.
Moving to KUnit has multiple benefits, such as:
- Consistency with the rest of the lib/crypto/ tests.
- Kernel developers familiar with KUnit, which is used kernel-wide, can
quickly understand the test and how to enable and run it.
- The test will be automatically run by anyone using
lib/crypto/.kunitconfig or KUnit's all_tests.config.
- Results are reported using the standard KUnit mechanism.
- It eliminates one of the few remaining back-references to crypto/ from
lib/crypto/, specifically a reference to CONFIG_CRYPTO_SELFTESTS.
