Summary:
## Context
In dev mode, Metro hijacks the JavaScript `console`, and prints all logs into the terminal running the Metro server.
## Problem
We have no way to distinguish between Bridge mode and Bridgeless mode logs. This makes it hard to tell catch warnings and errors are coming from bridgeless mode.
## Changes
- This diff adds a "NOBRIDGE" prefix to all React Native Metro logs coming from Bridgeless mode.
- Bridge mode console logs/warnings/errors are **unaffected**.
