lib/crypto: hash_info: Move hash_info.c into lib/crypto/
crypto/hash_info.c just contains a couple of arrays that map HASH_ALGO_*
algorithm IDs to properties of those algorithms. It is compiled only
when CRYPTO_HASH_INFO=y, but currently CRYPTO_HASH_INFO depends on
CRYPTO. Since this can be useful without the old-school crypto API,
move it into lib/crypto/ so that it no longer depends on CRYPTO.
This eliminates the need for FS_VERITY to select CRYPTO after it's been
converted to use lib/crypto/.
