Add a SHA3 kunit test suite, providing the following:
(*) A simple test of each of SHA3-224, SHA3-256, SHA3-384, SHA3-512,
SHAKE128 and SHAKE256.
(*) NIST 0- and 1600-bit test vectors for SHAKE128 and SHAKE256.
(*) Output tiling (multiple squeezing) tests for SHAKE256.
(*) Standard hash template test for SHA3-256. To make this possible,
gen-hash-testvecs.py is modified to support sha3-256.
(*) Standard benchmark test for SHA3-256.
[EB: dropped some unnecessary changes to gen-hash-testvecs.py, moved
addition of Testing section in doc file into this commit, and
other small cleanups]

Add SHA-3 support to lib/crypto/. All six algorithms in the SHA-3
family are supported: four digests (SHA3-224, SHA3-256, SHA3-384, and
SHA3-512) and two extendable-output functions (SHAKE128 and SHAKE256).
The SHAKE algorithms will be required for ML-DSA.
[EB: simplified the API to use fewer types and functions, fixed bug that
sometimes caused incorrect SHAKE output, cleaned up the
documentation, dropped an ad-hoc test that was inconsistent with
the rest of lib/crypto/, and many other cleanups]
