RFR: 8370885: Default namedGroups values are not being filtered against algorithm constraints [v2]

[Artur Barashev]

> NamedGroup.SupportedGroups.namedGroups values are not being filtered against algorithm constraints, unlike other SSLParameters returned by SSLConfiguration#getSSLParameters() call. Those are the values being displayed to the user with "java -XshowSettings:security:tls" command.
> 
> Also making changes to avoid needless default group names lookup while we are touching this file.
