RFR: 8359958: Cleanup "local" debuggee references after JDK-8333117 removed support for non-local debuggees [v2]

[Chris Plummer]

> [JDK-8333117](https://bugs.openjdk.org/browse/JDK-8333117) removed support for non-local debuggees, so now only local debuggees are supported. However, there are now a lot of references to the "local" debuggee mode which are not necessary because "local" is implied. These references are in comments and API names and should be removed.
> 
> Also, after [JDK-8333117](https://bugs.openjdk.org/browse/JDK-8333117), DebugeeProcess no longer needs to be considered abstract. It has no abstract methods.
> 
> Tested nsk/jdi, nsk/jdb, and nsk/jdwp locally. Will run tier5 CI to get better coverage.
