Radu Berinde bdde10137b hash/crc32: cleanup code and improve tests
Major reorganization of the crc32 code:

 - The arch-specific files now implement a well-defined interface
   (documented in crc32.go). They no longer have the responsibility of
   initializing and falling back to a non-accelerated implementation;
   instead, that happens in the higher level code.

 - The non-accelerated algorithms are moved to a separate file with no
   dependencies on other code.

 - The "cutoff" optimization for slicing-by-8 is moved inside the
   algorithm itself (as opposed to every callsite).

Tests are significantly improved:
 - direct tests for the non-accelerated algorithms.
 - "cross-check" tests for arch-specific implementations (all archs).
 - tests for misaligned buffers for both IEEE and Castagnoli.

Fixes #16909.
