We just left everything for QLibraryStore::cleanup() to do when that ran at QtCore unload time. Which is certainly weird because that meant no other library could be unloaded if it was a dependency of a plugin we'd loaded. Now, this should allow the libraries to start unloading before QtCore, when the Q_GLOBAL_STATICs holding the QFactoryLoaders get destroyed by ::exit(). This also explicitly deletes the instances in each of those dynamic plugins, otherwise they may remain around and cause crashes later. This is not done for instances coming from staticplugins - see next commit.
