If Chrome is available to handle Browser Action request, the context menu opened should share the same UI as Chrome context menu. So Browser Action need to share the logic about populating data and show UI with Chrome context menu. To achieve that, context menu logic on Chrome need to refactor to adapt needs for Browser Action. It mainly comes from two pieces:

1. Capable to trigger context menu from Java side.
2. Capable to support custom items with custom Bitmap icons, strings and action defined in PendingIntent.
