Add ContentLoadingProgressBar support

ContentLoadingProgressBar allows developers to follow the policy for loading content
laid out in the style guide. The progress view will only show if MIN_DELAY
passes before the view is hidden. The progress view, if shown, will always
show for at least MIN_SHOW_TIME ms.
