rgw: write RGW_ATTR_CRYPT_PREFETCH_ALIGN for AEAD ciphers

Store the plaintext and encrypted block sizes at upload time so
future cls prefetch ops can compute on-disk read ranges from
xattrs without instantiating a cipher.

Only written for size-expanding ciphers (GCM). CBC objects have
no attr — plaintext and ciphertext sizes are identical.
