lib/crypto: tests: Add KUnit tests for SHA-224 and SHA-256 



Add KUnit test suites for the SHA-224 and SHA-256 library functions,
including the corresponding HMAC support.  The core test logic is in the
previously-added hash-test-template.h.  This commit just adds the actual
KUnit suites, and it adds the generated test vectors to the tree so that
gen-hash-testvecs.py won't have to be run at build time.

	  Include benchmarks in the KUnit tests for cryptographic functions.

	  The benchmark results are printed to the kernel log when the

	  corresponding KUnit test suite runs.



	  This is useful for evaluating the performance of the cryptographic

	  functions.  However, it will increase the runtime of the KUnit tests.



	  If you're only interested in correctness testing, leave this disabled.
