RFR: 8349583: Add mechanism to disable signature schemes based on their TLS scope [v12]

[Artur Barashev]

> Currently when a signature scheme constraint is specified with "jdk.tls.disabledAlgorithms" property we don't differentiate between signatures used to sign a TLS handshake exchange and the signatures used in TLS certificates:
> https://datatracker.ietf.org/doc/html/rfc8446#section-4.2.3
> 
> Also fixing JDK-8350807 on the server side just as a side-effect, not a dedicated fix for that issue.
