<AWT Dev> RFR: 8257853: Remove dependencies on JNF's JNI utility functions in AWT and 2D code

[Phil Race]

This defines some macros to support declaring and initialising statically allocated instances of jclass, jmethodID and jfieldID
and changes many existing uses of JNF macros/functions to use these instead.
Then calls to JNFCall* and JNFNewObject - etc are updated to directly call JNI methods
JNI exception checking macros are added as needed.
