DevTools: [Persistence] introduce badged icons instead of checkmarks
This patch introduces badged icons instead of green checkmarks.
To achieve this, this CL does:
- introduce a bunch of new icons
- introduce UI.Icon.combine method, which overlays an array of icons atop
of each other. The result of this operation is a span which has dimensions
of the first icon.
