Adjust ChatNotificationSender consider the CBM feature flag

Use the old link when it's off. Use a separate inbox or a conversation
specific link depending on if the notification itself contains the
conversationId in there or not.

Also replace the TaskStackBuilder with a simple
PendingIntent.getActivity since we simply have one activity to open, and
we pass it a deep link instead.
