Some more includes to .inline.hpp files in gc header files

We should not include .inline.hpp files in .hpp files, but anyway a few of those crept in lately in gc code:

src/hotspot//share/gc/shared/workerManager.hpp:#include "runtime/os.inline.hpp"
src/hotspot//share/gc/shared/workerManager.hpp:#include "runtime/thread.inline.hpp"
src/hotspot//share/gc/shared/parallelCleaning.hpp:#include "classfile/classLoaderDataGraph.inline.hpp"
src/hotspot//share/gc/shenandoah/shenandoahTaskqueue.hpp:#include "gc/shared/taskqueue.inline.hpp"
src/hotspot//share/gc/shenandoah/shenandoahStringDedup.hpp:#include "classfile/javaClasses.inline.hpp"

Fix them.
