Add MessagingStyle#isGroupConversation().

This will allow apps to mark a Notification's MessagingStyle as a group
conversation. This is useful because the current implementation
overloads MessagingStyle#conversationTitle; which, when not null,
implies a group conversation. Instead of relying on this implicit
contract, we include this change's explicit field.
