lib/crypto: arm64/aes: Migrate optimized code into library

Move the ARM64 optimized AES key expansion and single-block AES
en/decryption code into lib/crypto/, wire it up to the AES library API,
and remove the superseded crypto_cipher algorithms.

The result is that both the AES library and crypto_cipher APIs are now
optimized for ARM64, whereas previously only crypto_cipher was (and the
optimizations weren't enabled by default, which this fixes as well).

Note: to see the diff from arch/arm64/crypto/aes-ce-glue.c to
lib/crypto/arm64/aes.h, view this commit with 'git show -M10'.
