Add local wallpaper color extraction to folder backgrounds.
- Starts listening to local wallpaper colors as soon as folder
is positioned.
- The folder open animation already has a background color
animator.
- For simplicity, folder open animation always starts
first, and then we cancel its background color animator,
and start a new animator to the extracted color.
- setAutoCancel would be handy here, but it does not work, will
track in a separate bug.
- Since folders are reused, we clear our the color extractor on
folder close.
Bug: 175329686
Test: multiple folders on rainbow background
open each folder, ensure bg animates to proper color
