feat: improve perf and avoid updating data or view when not necessary

[kristw]

• Update data only when new view is created or data is changed (checked by shallow equality)
• Create new view only when view parameters are changed (excluding style, className and perform shallow equality check on signalHandlers to avoid developer accidentally passing newly created object every time and got huge perf issue.)
