The coverage tool revealed that we weren't testing all codepaths of the ChaCha
assembly. Add a standalone test as it's much easier to iterate over all lengths
when there isn't the entire AEAD in the way.
I wasn't able to find a really long test vector, so I generated a random one
with the Go implementation we have in runner.
This test gives us full coverage on the ChaCha20_ssse3 variant. (We'll see how
it fares on the other codepaths when the multi-variant test harnesses get in. I
certainly hope there isn't a more novel way to call ChaCha20 than this...)

This is in preparation for adding AES_256_GCM in Chromium below AES_128_GCM.
For now, AES_128_GCM is preferable over AES_256_GCM for performance reasons.
While I'm here, swap the order of 3DES and RC4. Chromium has already disabled
RC4, but the default order should probably reflect that until we can delete it

Both sides' signature and Finished checks still occur, but the results
are ignored. Also, all ciphers behave like the NULL cipher.
Conveniently, this isn't that much code since all ciphers and their size
computations funnel into SSL_AEAD_CTX.
This does carry some risk that we'll mess up this code. Up until now, we've
tried to avoid test-only changes to the SSL stack.
There is little risk that anyone will ship a BORINGSSL_UNSAFE_FUZZER_MODE build
for anything since it doesn't interop anyway. There is some risk that we'll end
up messing up the disableable checks. However, both skipped checks have
negative tests in runner (see tests that set InvalidSKXSignature and
BadFinished). For good measure, I've added a server variant of the existing
BadFinished test to this CL, although they hit the same code.
