However, for now, we will only enable it if TLS 1.3 is offered.

TLS 1.3 will go through very different code than everything else. Even
SSL 3.0 is somewhat special-cased now. Move the invalid signature tests
there and run at all versions.

ServerKeyExchange and SigningHash are both very 1.2-specific names.
Replace with names that fit both 1.2 and 1.3 (and are a bit shorter).
Also fix a reference to ServerKeyExchange in sign.go.

Now that the odd client/server split (a remnant from the original
crypto/tls code not handling signing-hash/PRF mismatches) is gone, it
can just be pulled from the config.

Saves worrying about forgetting it. (And indeed I forgot it in the TLS
1.3 code.)

(Of course, it's still signing ServerKeyExchange messages since the
handshake's the old one.)

Implement in both C and Go. To test this, route config into all the
sign.go functions so we can expose bugs to skip the check.
Unfortunately, custom private keys are going to be a little weird since
we can't check their curve type. We may need to muse on what to do here.
Perhaps the key type bit should return an enum that includes the curve?
It's weird because, going forward, hopefully all new key types have
exactly one kind of signature so key type == sig alg == sig alg prefs.

TLS 1.3 defines a new SignatureScheme uint16 enum that is backwards
compatible on the wire with TLS1.2's SignatureAndHashAlgorithm. This
change updates the go testing code to use a single signatureAlgorithm
enum (instead of 2 separate signature and hash enums) in preparation for
TLS 1.3. It also unifies all the signing around this new scheme,
effectively backporting the change to TLS 1.2.
For now, it does not distinguish signature algorithms between 1.2 and
1.3 (RSA-PSS instead of RSA-PKCS1, ECDSA must match curve types). When
the C code is ready make a similar change, the Go code will be updated
to match.
