RFR: 8350582: Correct the parsing of the ssl value in javax.net.debug [v3]

[Sean Coffey]

> Breaking the parent JDK-8044609 JBS issue into sub tasks. 
> 
> This patch addresses the main issue which is that `javax.net.debug=ssl ` option is completely broken since TLSv1.3 support was introduced.  This patch should be easier for backporting also.
> 
> Wider corrections can be followed up via parent bug.
