Use oslogger for macOS logging (#891)

## 🎟️ Tracking

<!-- Paste the link to the Jira or GitHub issue or otherwise describe /

## 📔 Objective

Xcode doesn't seem to be able to pick up `stdio` logs from secondary
processes like autofill extensions. This PR switches to using native iOS
logging which Xcode supports.
