Adds a traitCollectionDidChangeBlock to MDCFeatureHighlightViewController and MDCFeatureHighlightView, called when its trait collection changes. Additionally this moves the FeatureHighlightView test to a more generic name, instead of FeatureHighlightNoopTests they were moved to FeatureHighlightViewTests. Closes #8050
