Description

Handle unreasonably large favicons gracefully, by setting a max size in pixels.

Steps to test this PR

1. Start a local HTTP server serving a page with a large apple-touch-icon:
   cd /tmp/favicon_test && python3 -m http.server 8888 (The test page serves a 6708×6708 PNG as its touch icon)
2. On the device, open the DuckDuckGo browser and navigate to http://{your-server-ip}:8888
3. Wait ~2 seconds for the touch icon to be discovered and downloaded
4. Open the tab switcher
5. Without the changes: App crashes with:
   RuntimeException: Canvas: trying to draw too large(179989056bytes) bitmap But with the changes shouldn't crash.

Note

Low Risk
Small, localized change that only constrains favicon bitmap dimensions; low risk aside from potential quality reduction for very large icons.

Overview
Prevents crashes from unreasonably large favicons by introducing a MAX_FAVICON_SIZE_PX cap (512px) and enforcing it across Glide favicon fetches.

Both async (CustomTarget) and sync (submit) download paths for disk and URL loads now request bitmaps at the capped size, limiting memory usage during decoding/rendering.
