Android: Run Node.js based on native App lifecycle

• Run Node.js based on native App lifecycle
• Remove Capacitor-nodejs dependency
• Capacitor Bridge is not used anymore since Node.js runs a local server

I built it on github CI and installed it on a real Android device (where Mustang Android from master is already running well), and it's crashing on startup.

Sorry, I haven't written the code to download the libnode to the project. And there's also a linking error I'm seeing whenever the libnode is missing you have to open Android Studio to relink it.

Also this got broken again since 57843e6 because I was trying to reuse the V8 instance so when the app pauses we can stop node but not reinitialize V8.

The functions to start and stop Node.js work now but both are too slow.

When the startup is too slow, it causes the frontend to throw an error stating that the backend is not present.

When stopping Node.js is too slow, it causes the app to crash because the old Node.js instance is still present. But this only happens when tap the back button to exit and quickly open the app again.

I've rebased to master.
