feat: [FC-0070] add message events to the unit page container

[ihor-romaniuk]

🚨 Dependencies:

• 🔗 frontend-app-authoring [MERGED]
• 🔗 edx-platform [MERGED]

Description

This feature introduces two main functionalities to improve XBlock interactions within iframes:

• Add an event listener to the window object that listens for messages of type refreshXBlock. Upon receiving such a message, the render() method is called to refresh the current XBlock.
• When the isIframeEmbed option is enabled, the XBlock sends a postMessage to the parent window. This message contains information about the source XBlock and its parent, triggering a modal display in the parent context.
