crypto: simd - support wrapping AEAD algorithms
Update the crypto_simd module to support wrapping AEAD algorithms. Previously it only supported skciphers. The code for each is similar. I'll be converting the x86 implementations of AES-GCM, AEGIS, and MORUS to use this. Currently they each independently implement the same functionality. This will not only simplify the code, but it will also fix the bug detected by the improved self-tests: the user-provided aead_request is modified. This is because these algorithms currently reuse the original request, whereas the crypto_simd helpers build a new request in the original request's context.
