  lib/crypto: tests: Annotate worker to be on stack (2025-07-21 20:10:36 -0700)

----------------------------------------------------------------

Add KUnit test suites for the Poly1305, SHA-1, SHA-224, SHA-256,
SHA-384, and SHA-512 library functions.

These are the first KUnit tests for lib/crypto/. So in addition to
being useful tests for these specific algorithms, they also establish
some conventions for lib/crypto/ testing going forwards.

The new tests are fairly comprehensive: more comprehensive than the
generic crypto infrastructure's tests. They use a variety of
techniques to check for the types of implementation bugs that tend to
occur in the real world, rather than just naively checking some test
vectors. (Interestingly, poly1305_kunit found a bug in QEMU.)

The core test logic is shared by all six algorithms, rather than being
duplicated for each algorithm.

Each algorithm's test suite also optionally includes a benchmark.
