RFR: 8286185: The Java manpage can be more platform inclusive [v3]

[David Holmes]

> This is mainly an expansion of the included platforms by changing "linux and macOS" to "Non-Windows". There are a few additional examples, and clarification that they are just examples. There are also some minor edits and corrections I spotted.
> 
> One actual fix relates to the "control-break" -> "control-" change. I can factor that out if needed (or just add an additional issue to the PR).
> 
> This doesn't attempt to give complete platform recognition for all OpenJDK platforms. Two areas where anyone interested could file a further RFE is the support of DTrace on BSD systems other than macOS; and the use of RTM locking on Power8 architecture (existing documentation is all about Intel TSX on x86).
