hashes: Add NIST CAVP test vectors

Add SHAVS test vectors for SHA-1, SHA-256, SHA-384, SHA-512,
SHA-512/256, and SHA3-256.
Each hash is tested with both one-shot and byte-by-byte incremental
hashing against official ShortMsg and LongMsg .rsp files

The short version

What changed, and why it matters

This commit only adds new test data and test code. It imports official NIST cryptographic test vectors for several hash algorithms and writes tests that compare the library's output against those known correct answers. There is no change to the actual hashing code, no bug fix, and no security-relevant behavior change.

Recommended action

No action required; this is a test-only addition. Reviewers may optionally verify the test vectors are genuine NIST CAVP files and that the incremental test exercises the intended update boundaries.

Security signals we found

No strong security signals were identified.
