Add accelerated arm64 sha512 to libmd

Description

Add accelerated arm64 sha512 to libmd

As with sha256 add support for accelerated sha512 support to libmd on
arm64. This depends on clang 13+ to build as this is the first release
with the needed intrinsics. Gcc should also support them, however from
a currently unknown release.
