Move the ChaCha20Poly1305 test from an ad-hoc self-test to a KUnit test.
Keep the same test logic for now, just translated to KUnit.
Moving to KUnit has multiple benefits, such as:
- Consistency with the rest of the lib/crypto/ tests.
- Kernel developers familiar with KUnit, which is used kernel-wide, can
quickly understand the test and how to enable and run it.
- The test will be automatically run by anyone using
lib/crypto/.kunitconfig or KUnit's all_tests.config.
- Results are reported using the standard KUnit mechanism.
- It eliminates one of the few remaining back-references to crypto/ from
lib/crypto/, specifically a reference to CONFIG_CRYPTO_SELFTESTS.

Add a KUnit test suite for the SM3 library. It closely mirrors the test
suites for the other cryptographic hash functions. The actual test and
benchmark logic is already in hash-test-template.h; this just wires it
up for SM3 in the usual way.

Add a KUnit test suite for the GHASH library functions.
It closely mirrors the POLYVAL test suite.

For kunit.py to run all the crypto library tests when passed the
--alltests option, tools/testing/kunit/configs/all_tests.config needs to
enable options that satisfy the test dependencies.
This is the same as what lib/crypto/.kunitconfig already does.
However, the strategy that lib/crypto/.kunitconfig currently uses to
select all the hidden library options isn't going to scale up well when
it needs to be repeated in two places.
Instead let's go ahead and introduce an option
CRYPTO_LIB_ENABLE_ALL_FOR_KUNIT that depends on KUNIT and selects all
the crypto library options that have corresponding KUnit tests.
Update lib/crypto/.kunitconfig to use this option.

Add a .kunitconfig file to the lib/crypto/ directory so that the crypto
library tests can be run more easily using kunit.py. Example with UML:
tools/testing/kunit/kunit.py run --kunitconfig=lib/crypto
Example with QEMU:
tools/testing/kunit/kunit.py run --kunitconfig=lib/crypto --arch=arm64 --make_options LLVM=1
