Allow static libs

- Remove SHARED option from add_library to allow static libs, CMake then respects the standard BUILD_SHARED_LIBS option. - Set the default value of BUILD_SHARED_LIBS to ON. - Modify plugin_manager_impl to call the plugin init function for built-in plugins via a hook, whilst still supporting external shared library plugins. - Add plugin init hook function to each built-in plugin. - Add plugin libs to link libs in CMake export config when static libs are enabled.
