crypto-native: fix build error on Arm using clang-13
Building VPP on Arm using clang-13 as compiler will fail with following
error message. The root cause is the unmatched alignment of parameter
key for functions aes128_key_expand/aes256_key_expand on aarch64.
Fix this error by explicitly declaring parameter key as type u8x16u.
