<Sound Dev> RFR: 8254798: Deprecate for removal an empty finalize() methods in java.desktop module

[Sergey Bylokhov]

The java.desktop module has a few implementations of the finalize() method which do nothing. We can remove such methods
if the class is not public API, and could mark these methods in the public classes as "forRemoval = true"
