Fix unbundled accessibility features settings crash when launched

Root cause: The ag/19938064 introduces Settings Core change preference value changed metrics log format. It tries to lookupMetricsCategory() at Fragment#instantiate() stage. It has not onAttach() to activity by FragmentManager#add() or #replace(). The features were added by ag/15824482.
Solution: PutInt new MATRICS_CATEGORY extra in previous class to avoid giving context for FeatureFactory.getFactory to custom 1P accessibility services for SettingsGoogle overlay.
