Instead of providing crypto_shash algorithms for the arch-optimized SHA-256 code, instead implement the SHA-256 library. This is much simpler, it makes the SHA-256 library functions be arch-optimized, and it fixes the longstanding issue where the arch-optimized SHA-256 was disabled by default. SHA-256 still remains available through crypto_shash, but individual architectures no longer need to handle it. Remove support for SHA-256 finalization from the ARMv8 CE assembly code, since the library does not yet support architecture-specific overrides of the finalization. (Support for that has been omitted for now, for simplicity and because usually it isn't performance-critical.) To match sha256_blocks_arch(), 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 and NEON assembly functions actually already treated it as size_t. While renaming the assembly files, also fix the naming quirks where "sha2" meant sha256, and "sha512" meant both sha256 and sha512.
