lib/crc: arm64: Simplify intrinsics implementation (2026-04-02 16:14:53 -0700)

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

- Several improvements related to crc_kunit, to align with the standard KUnit conventions and make it easier for developers and CI systems to run this test suite

- Add an arm64-optimized implementation of CRC64-NVME

- Remove unused code for big endian arm64

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