Make GPluginManager a final type

* Use g_signal_new_class_handler to handle the accumulator based signals
* Remove the optional struct offset for the non accumulator based signals
* This all fixes the warnings from vapigen as well

Testing Done:
Ran the unit tests, gplugin-query, and gplugin-gtk3-viewer without issue.
