* feat(chatgpt-browser.js, askBingAI.js, askChatGPTBrowser.js): add onEventMessage callback to browserClient

Add onEventMessage callback to browserClient to handle event messages from the server. In askChatGPTBrowser.js, add a getPartialMessage variable to store the partial message text. In askBingAI.js, fix a typo in the variable name newUserMassageId to newUserMessageId. In askChatGPTBrowser.js, remove the preSendRequest parameter and move the sendMessage call to the onEventMessage callback. In askChatGPTBrowser.js, add a check for null or undefined value of getPartialMessage before appending it to the error message.
