https://linear.app/comm/issue/ENG-8674/track-progress-of-sending-tunnelbroker-messages

Depends on D12776

Test Plan:
Tested on both native and web. Added some code

await this.props.p2p.sendDMOperation({
  op: {
    type: 'send_text_message',
    threadID: messageInfo.threadID,
    creatorID: messageInfo.creatorID,
    time: messageInfo.time,
    messageID: getUUID(),
    text: messageInfo.text,
  },
  supportsAutoRetry: false,
  recipients: 'self_devices',
});

to input state containers so that it is called after sending messages. Checked if the second device received a message after sending a text message.
