Instead of exposing the arm64-optimized SM3 code via arm64-specific crypto_shash algorithms, instead just implement the sm3_blocks() library function. This is much simpler, it makes the SM3 library functions be arm64-optimized, and it fixes the longstanding issue where the arm64-optimized SM3 code was disabled by default. SM3 still remains available through crypto_shash, but individual architectures no longer need to handle it. Tweak the SM3 assembly function prototypes to match what the library expects, including changing the block count from 'int' to 'size_t'. sm3_ce_transform() had to be updated to access 'x2' instead of 'w2', while sm3_neon_transform() already used 'x2'. Remove the CFI stubs which are no longer needed because the SM3 assembly functions are no longer ever indirectly called. Remove the dependency on KERNEL_MODE_NEON. It was unnecessary, because KERNEL_MODE_NEON is always enabled on arm64.
