[webcomponents] Custom elements need an explicit "upgraded" or "resolved" flag (#425)

This will be used for CSS to match against.

Questions:

- Is it "upgraded", or "resolved"? See #418.
- Are there any concerns with setting this flag immediately upon upgrade? (That is, at nanotask time.) It seems like it would cause sync layout, which is usually not great?
