Summary
-------

Deprecate for removal empty finalize() methods in the java.desktop module previously deprecated in JDK 9 under JDK-8165641.

Problem
-------

The java.desktop module has a few implementations of the finalize() method which do nothing. We can mark these methods as "forRemoval = true".

Solution
--------

The solution is to deprecate this API in jdk16 and remove it later.
