[Favicon] Add FallbackIconStyle and FallbackIconService.
Design: go/chrome-fallback-icons
This implements
- FallbackIconStyle: A struct to specify fallback data.
- FallbackIconService: Helper class to render the fallback icon as a
filled rounded square with a single letter from the URL.
- Extra dependencies are needed to convert URL to the icon letter.
