Subject: Disable AppRating

Chromium Android includes an AppRating promo path that can trigger user-facing
review prompts through the Android app-rating integration. The implementation
depends on Google Play Review APIs provided by Google Play Services. Those
dependencies are already excluded by default in this fork through a separate
patch, making the AppRating feature non-functional and unnecessary.

Change:
Remove AppRatingPromoController from the optional promo selection flow and
exclude the app_rating Java and junit targets from the Android build graph.

Privacy/Security Impact:
Removes an unused user-engagement surface and avoids invoking review-related
logic tied to Google Play Services. No browser engine, network, Blink, V8,
storage, or process-isolation behavior is changed.

Notes:
AppRating depends on Google Play Review APIs from Google Play Services.
Since Google Play Services support is already excluded by default through a
separate patch, this change removes the now-unused integration and prevents
accidental reintroduction of the feature.
