Filippo Valsorda fcc990c556 ssh: deprecate and replace SigAlgo constants 
RFC 8332, Section 2 sets up two overlapping namespaces: public key
formats and public key algorithms.

* The formats are what we currently have KeyAlgo constants for, and they
  appear in PublicKey.Type.

* The algorithms are the set of both KeyAlgo and SigAlgo constants, and
  they appear in Signature.Format (amongst other places).

This is incoherent, because that means Signature.Format can be both a
KeyAlgo (like KeyAlgoECDSA256) or a SigAlgo (like SigAlgoRSASHA2256).

One solution would be to duplicate all the KeyAlgo constants into the
SigAlgo namespace, but that would be confusing because applications are
currently using KeyAlgos where they'd be supposed to use the new
SigAlgos (while we can't deprecate the KeyAlgos because they are still
necessary for the PublicKey.Type namespace).

Instead, drop the separate namespaces, and use KeyAlgos throughout.
There are simply some KeyAlgos that can't be a PublicKey.Type.

Take the opportunity to fix the stuttering SHA22565/SHA2512 names. It's
totally ok to call those hashes SHA-256 and SHA-512 without the family
infix.

For golang/go#49952

Hans Nielsen b4de73f9ec ssh: support RSA SHA-2 (RFC8332) signatures 
This change adds support for RSA SHA-2 based signatures for host keys and certificates. It also switches the default certificate signature algorithm for RSA to use SHA-512. This is implemented by treating ssh.Signer specially when the key type is `ssh-rsa` by also allowing SHA-256 and SHA-512 signatures.

Fixes golang/go#37278
