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
