RFR: 8260616: Removing remaining JNF dependencies in the java.desktop module [v4]

[Phil Race]

> This completes the desktop module JNF removal
> 
> * remove  -framework JavaNativeFoundation from make files
> 
> * remove  #import <JavaNativeFoundation/JavaNativeFoundation.h> from all source files. If needed add import of JNIUtilities.h to get jni.h definitions - better anyway since then it gets the current JDK ones not the ones from the O/S
> 
> * replace JNFNSToJavaString with NSStringToJavaString and  JNFJavaToNSString with JavaStringToNSString
> 
> * replace JNFNormalizedNSStringForPath with NormalizedPathNSStringFromJavaString and JNFNormalizedJavaStringForPath with NormalizedPathJavaStringFromNSString
> 
> * replace JNFGet/ReleaseStringUTF16UniChars with direct calls to JNI
> 
> * Map all JNFRunLoop perform* calls to the ThreadUtilities versions (the vast majority already did this)
> 
> * Redo the ThreadUtilities calls to JNFRunLoop to directly invoke NSObject perform* methods.
> 
> * define new javaRunLoopMode in ThreadUtilities to replace the JNF one and use where needed.
> 
> * Remove the single usage of JNFPerformEnvBlock
> 
> * replace JNFJavaToNSNumber in single A11Y file with local replacement
> 
> * replace single usage of JNFNSTimeIntervalToJavaMillis in ScreenMenu.m with local replacement
> 
> * remove un-needed JNFRunLoopDidStartNotification from NSApplicationAWT.m
> 
> * misc. remaining cleanup (eg missed JNF_CHECK_AND_RETHROW_EXCEPTION)
