Feature Description

When messages in a conversation are cleared, all the messages in the conversation will be cleared both locally and from the cloud, but the conversation itself will not be deleted.
Note:
1. When messages in a conversation are cleared, unreadCount will be set to 0, and the content of lastMessage will be cleared as well.
2. This API cannot be used to clear messages in a topic.
