Add simple hand-rolled RTTI for Pepper ResourceHosts
This allows Pepper ResourceHosts to be safely dynamically cast to a given type. For example, you may have a PP_Resource provided by the plugin which corresponds to a ResourceHost object which should be of type X. But statically casting to type X would be unsafe because the plugin is untrusted.
I've kept this simple for now because we don't have too many types which need to be dynamically cast. To add RTTI for a new class, you need to add a new AsPepperXXXHost virtual function in ResourceHost and override it in your derived class.
This also cleans up the previous RTTI checks for Graphics2D and the unsafe checks that were being used for FileSystem.
