crypto: arm64/sha3 - Update sha3_ce_transform() to prepare for library

- Use size_t lengths, to match the library.

- Pass the block size instead of digest size, and add support for the
  block size that SHAKE128 uses.  This allows the code to be used with
  SHAKE128 and SHAKE256, which don't have the concept of a digest size.
  SHAKE256 has the same block size as SHA3-256, but SHAKE128 has a
  unique block size.  Thus, there are now 5 supported block sizes.

Don't bother changing the "glue" code arm64_sha3_update() too much, as
it gets deleted when the SHA-3 code is migrated into lib/crypto/ anyway.
