[jdk11u-dev] RFR: 8266967: debug.cpp utility find() should print Java Object fields.

[Goetz Lindenmaier]

I backport this for parity with 11.0.18-oracle.

I had to resolve one hunk in instanceKlass.cpp because there
is more debug coding in 16.

Further I had to resolve fieldDescriptor.hpp because of context
and copyright.
