lib/crypto: arm64/sha512: Migrate optimized SHA-512 code to library
Instead of exposing the arm64-optimized SHA-512 code via arm64-specific
crypto_shash algorithms, instead just implement the sha512_blocks()
library function. This is much simpler, it makes the SHA-512 (and
SHA-384) library functions be arm64-optimized, and it fixes the
longstanding issue where the arm64-optimized SHA-512 code was disabled
by default. SHA-512 still remains available through crypto_shash, but
individual architectures no longer need to handle it.
To match sha512_blocks(), change the type of the nblocks parameter of
the assembly functions from int or 'unsigned int' to size_t. Update the
ARMv8 CE assembly function accordingly. The scalar assembly function
actually already treated it as size_t.
