Backport crypto and CRC KUnit improvements

This series backports improvements to the KUnit testing for the crypto and CRC libraries to 6.18, including:

- Finish fixing the test kconfig options to follow standard conventions
- Add kunitconfig files
- Make the tests be included in 'kunit.py run --alltests'

The crypto patches were adjusted to drop parts that pertain to tests added in later kernels.

While stable backports are normally limited to "fixes", I think it's worth also backporting the kunitconfig files and the all_tests.config support, since these are safe test-only changes that are helpful for testing 6.18. For example, this should make KernelCI run all these tests on 6.18, as it uses 'kunit.py run --alltests'.
