Modify sigalgs extension processing for TLS 1.3.

- Make a separate sigalgs list for TLS 1.3 including only modern
  algorithm choices which we use when the handshake will not negotiate
  TLS 1.2
- Modify the legacy sigalgs for TLS 1.2 to include the RSA PSS algorithms as
  mandated by RFC8446 when the handshake will permit negotiation of TLS 1.2
