[DX] AsyncMessaging: explore two-way sync

[cuserox]

📚 Context

We need better handling of async messages, it's spread across a number of different files instead of being easy to understand. Ideally we'd have a two-way sync that we can call from both the plugin and the controller without a huge overhead.

🛠 Acceptance Criteria

• Explore other libraries and projects that do this well:
  • https://github.com/martynaskadisa/figma-comlink
  • https://github.com/labXD/trpc-figma
  • https://github.com/CoconutGoodie/monorepo-networker
• Discuss and ideate on a plan to replace our current setup
• PoC it and document
