Move the Curve25519 test from an ad-hoc self-test to a KUnit test.
Generally keep the same test logic for now, just translated to KUnit.
There's one exception, which is that I dropped the incomplete test of
curve25519_generic(). The approach I'm taking to cover the different
implementations with the KUnit tests is to just rely on booting kernels
in QEMU with different '-cpu' options, rather than try to make the tests
(incompletely) test multiple implementations on one CPU. This way, both
the test and the library API are simpler.
This commit makes the file lib/crypto/curve25519.c no longer needed, as
its only purpose was to call the self-test. However, keep it for now,
since a later commit will add code to it again.
Temporarily omit the default value of CRYPTO_SELFTESTS that the other
lib/crypto/ KUnit tests have. It would cause a recursive kconfig
dependency, since the Curve25519 code is still entangled with CRYPTO. A
later commit will fix that.

Add a KUnit test suite for BLAKE2s. Most of the core test logic is in
the previously-added hash-test-template.h. This commit just adds the
actual KUnit suite, commits the generated test vectors to the tree so
that gen-hash-testvecs.py won't have to be run at build time, and adds a
few BLAKE2s-specific test cases.
This is the replacement for blake2s-selftest, which an earlier commit
removed. Improvements over blake2s-selftest include integration with
KUnit, more comprehensive test cases, and support for benchmarking.

Add a KUnit test suite for the Poly1305 functions. Most of its test
cases are instantiated from hash-test-template.h, which is also used by
the SHA-2 tests. A couple additional test cases are also included to
test edge cases specific to Poly1305.
