Polish WebView crash UI layout:
- Use android material theme and support dark theme.
- Use an expandable list to show crashes where we show the important
  info (package name and crash capture time in the header) and show
  variation keys, upload status, report button in the expanded body.
- Use a more descriptive string for the reporting button
  "File bug report" instead of "Provide more info".
- For better visualization, show app icon next to package name to
  be easy to find by eye.
- Use ListViewAdapter#notifyDataSetChanged() instead of creating
  new adapter to optimize crash list updates.
- Update MainActivity to use the new two_line_list_item layout.

Bug: 948923
Test: Manually inspect the UI on SystemWebView on Android P and Android Q with dark mode switched on/off.
