arm64/crc-t10dif: expose CRC-T10DIF function through lib
Move the arm64 CRC-T10DIF assembly code into the lib directory and wire
it up to the library interface. This allows it to be used without going
through the crypto API. It remains usable via the crypto API too via
the shash algorithms that use the library interface. Thus all the
arch-specific "shash" code becomes unnecessary and is removed.
