Migrate the arm-optimized BLAKE2b code from arch/arm/crypto/ to lib/crypto/arm/. This makes the BLAKE2b library able to use it, and it also simplifies the code because it's easier to integrate with the library than crypto_shash. This temporarily makes the arm-optimized BLAKE2b code unavailable via crypto_shash. A later commit reimplements the blake2b-* crypto_shash algorithms on top of the BLAKE2b library API, making it available again. Note that as per the lib/crypto/ convention, the optimized code is now enabled by default. So, this also fixes the longstanding issue where the optimized BLAKE2b code was not enabled by default. To see the diff from arch/arm/crypto/blake2b-neon-glue.c to lib/crypto/arm/blake2b.h, view this commit with 'git show -M10'.
