Revert 217109 "OmniboxPopupViewMac refactoring Part 3 (truncation)"

> OmniboxPopupViewMac refactoring Part 3 (truncation)
>
> This CL changes how omnibox popup results are truncated. Previously content
> text would be truncated at 70% which might leave empty space if the description
> was short. I've made the following changes to the truncation code:
>   - move the truncation logic to the button cell
>   - have the content text fill up unused space when truncating
>   - use a fade effect to truncate instead of ellipses
