Improved Java phantom references (#7131)

Browse source 
* Reworked phantom reference handling.
 - Replaced IDecRefQueue with a new Z3ReferenceQueue class
 - Z3ReferenceQueue manages custom subclasses of phantom references in a doubly-linked list
 - Replaced all subclasses of IDecRefQueue with subclasses of Z3ReferenceQueue.Reference. These custom reference classes are embedded in the class they reference count.
 - Context now owns a single Z3ReferenceQueue for all types of references.

* Made Statistics.Entry a static subclass

* Made Context.close idempotent (as recommended)

* Update CMakeLists.txt for building the Java API.

* Updated CMakeLists.txt again.

* Use correct SuppressWarning annotation to silence the compiler

* Formatting
