Changed paths:
M test/evp_aead_test.c
M test/evp_extra_test.c

Log Message:
-----------
test: migrate test_aes_siv_ctx_enc_retval from evp_extra_test.c to evp_aead_test.c

Move test_aes_siv_ctx_enc_retval() out of test/evp_extra_test.c into
test/evp_aead_test.c, rename it to test_evp_aead_enc_retval() and run
it over aead_list instead of only AES-128-SIV.

The check is that after a completed encrypt, a further
EVP_EncryptUpdate() on the same context is rejected,
and the EVP_EncryptFinal_ex() that follows fails as well,
instead of reporting the earlier success. GCM, OCB and ASCON mark
the context finished. SIV stores the result of the last operation,
so a rejected Update makes the following Final fail.

CCM, GCM-SIV and ChaCha20-Poly1305 are skipped: Final currently succeeds
after the rejected Update, and what it should do is not settled yet.
ChaCha20-Poly1305 reports the same mode as ASCON, so it is matched
by name.

Key and IV are sized from the resolved cipher parameters, the context
is set up with EVP_EncryptInit_ex2(), and the tag is fetched after Final
with OSSL_PARAM.
