Before RFC 7539 we had a ChaCha20-Poly1305 cipher suite that had a 64/64
nonce/counter split (as DJB's original ChaCha20 did). RFC 7539 changed
that to 96/32 and we've supported both for some time.
This change removes the old version and the TLS cipher suites that used

In doing so, regenerate the test RSA certificate to be 2048-bit RSA.
RSA-PSS with SHA-512 is actually too large for 1024-bit RSA. Also make
the sigalg test loop test versions that do and don't work which subsumes
the ecdsa_sha1 TLS 1.3 test.
For now, RSA-PKCS1 is still allowed because NSS has yet to implement
RSA-PSS and we'd like to avoid complicated interop testing.

Only ECDHE-based ciphers are implemented. To ease the transition, the
pre-standard cipher shares a name with the standard one. The cipher rule parser
is hacked up to match the name to both ciphers. From the perspective of the
cipher suite configuration language, there is only one cipher.
This does mean it is impossible to disable the old variant without a code
change, but this situation will be very short-lived, so this is fine.
Also take this opportunity to make the CK and TXT names align with convention.

This made sense when the cipher might have been standardized as-is, so a
DHE_RSA variant could appease the IETF. Since the standardized variant is going
to have some nonce tweaks anyway, there's no sense in keeping this around. Get
rid of one non-standard cipher suite value early. (Even if they were to be
standardized as-is, it's not clear we should implement new DHE cipher suites at
this point.)
Chrome UMA, unsurprisingly, shows that it's unused.
