libobs: Add obs_obj_invalid function
Determines whether an obs object was created successfully. If a plugin that's used for a saved object is removed (third party plugins), its data will become invalid, but the objects can often still be created for the sake of preserving user settings, but sometimes these objects can cause problems if they're actually used (such as using them for transitions).
