RFR: 8257988: Remove JNF dependency from libsaproc/MacosxDebuggerLocal.m [v2]

[Phil Race]

> This removes the JNF dependency from the jdk.hotspot.agent module.
> The macro expansions are the same as already used in the Java desktop module - which actually uses a macro
> still but there there are hundreds of uses.
> The function of this macro code is to prevent NSExceptions escaping to Java and also to drain the auto-release pool.
> What test group would be good for verifying this change ?
