~english Create Chat Thread.

Group members have permission. After chat thread is created, the following notices will appear:

1. Members of the organization (group) to which chat thread belongs will receive the created notification event, and can listen to related events by setting EMChatThreadEventHandler. The event callback function is EMChatThreadEventHandler.onChatThreadCreate.
2. Multiple devices will receive the notification event and you can set EMMultiDeviceEventHandler to listen on the event. The event callback function is EMMultiDeviceEventHandler.onChatThreadEvent, where the first parameter is the event, for example, EMMultiDevicesEvent.CHAT_THREAD_CREATE for the chat thread creation event.
