RFR: 8263323: Debug Agent help output includes invalid URL [v2]

[Chris Plummer]

> Rather than embed a URL in the help output, which needs to be updated if the location of docs ever changes, just include a description of the document so it can be looked up. The output now looks like:
> 
> 
> $ ./java -agentlib:jdwp=help
>                Java Debugger JDWP Agent Library
>                --------------------------------
> 
>   (See the "Oracle VM Invocation Options" section of the JPDA
>    "Connection and Invocation Details" document for more information.)
> 
> jdwp usage: java -agentlib:jdwp=[help]|[<option>=<value>, ...]
> 
> Option Name and Value            Description                       Default
