lib/crypto: riscv/aes: Migrate optimized code into library
Move the aes_encrypt_zvkned() and aes_decrypt_zvkned() assembly
functions into lib/crypto/, wire them up to the AES library API, and
remove the "aes-riscv64-zvkned" crypto_cipher algorithm.
To make this possible, change the prototypes of these functions to
take (rndkeys, key_len) instead of a pointer to crypto_aes_ctx, and
change the RISC-V AES-XTS code to implement tweak encryption using the
AES library instead of directly calling aes_encrypt_zvkned().
The result is that both the AES library and crypto_cipher APIs use
RISC-V's AES instructions, whereas previously only crypto_cipher did
(and it wasn't enabled by default, which this commit fixes as well).
