lib/crc_kunit.c: add KUnit test suite for CRC library functions
Add a KUnit test suite for the crc16, crc_t10dif, crc32_le, crc32_be,
crc32c, and crc64_be library functions. It avoids code duplication by
sharing most logic among all CRC variants. The test suite includes:
- Differential fuzz test of each CRC function against a simple
bit-at-a-time reference implementation.
- Test for CRC combination, when implemented by a CRC variant.
- Optional benchmark of each CRC function with various data lengths.
This is intended as a replacement for crc32test and crc16_kunit, as well
as a new test for CRC variants which didn't previously have a test.
