Set launch display id to an action performed on RemoteViews.

When user click notification's action (i.e. answer call), the activity
wouldn't display as the user is interacting with.
Add ActivityOptions#setLaunchDisplayId to the display that the given view
is currently on. So the activity will be launched to the display as the
user is interacting with.

Bug: 191222363
Test: Manually tested using Exo. Open calling application(e.g.WhatsApp)
on Exo virtual display, and answer the call from the notification of
phone.
