Generate code from app.json and avoid parsing JSON at runtime

[tido64]

Proposal

We currently parse app.json at runtime. However, app.json does not change at runtime, so it doesn't really make sense that we have to parse it at runtime either. Additionally:

• On some platforms, this requires additional dependencies (Moshi + KSP on Android, JSON for Modern C++ on Windows) that we have to keep up to date.
• On Android, there is additional maintenance overhead because KSP is tied to specific versions of Kotlin. In order to allow users to specify their own Kotlin version, we need to keep a list of supported KSP versions.

If we can generate code from app.json that we can embed directly in the app, we can eliminate the need for a JSON parser altogether.
