core: bring original volume panel expand icon back

This one makes more sense from a UX standpoint
Update the color of the expandable volume panel icon

This still retains the old settings icon since it
happens to fit perfectly. Pressing it does indeed
show you a bunch of sliders like the icon indicates.

Also add xhdpi and xxhdpi versions.
Fix: Linked volumes

Check for linked volumes a little earlier than we previously did.
This ensures the correct value is set after boot.
