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

Browse Source 
Move the ARM optimized single-block AES en/decryption code into
lib/crypto/, wire it up to the AES library API, and remove the
superseded "aes-arm" crypto_cipher algorithm.

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