Pull request description:

  This PR adds support for ARMv8 SHA2 Intrinsics.

  Fixes https://github.com/bitcoin/bitcoin/issues/13401 and https://github.com/bitcoin/bitcoin/issues/17414

  * Integration part was done by me.
  * The original SHA2 NI code comes from https://github.com/noloader/SHA-Intrinsics/blob/master/sha256-arm.c
  * Minor optimizations from https://github.com/rollmeister/bitcoin-armv8/blob/master/src/crypto/sha256.cpp are applied too.
  * The 2-way transform added by @sipa
