Web Inspector: make Spectrum and Popover WebInspector.Views in order to enable reuse

[Pavel Feldman]

- Split Spectrum and SpectrumPopoverHelper (first is a component, second it controller)
- Made Popover a root view in order to enable lazy style loading for potential subviews (such as Spectrum)
- Extracted spectrum's css into a separate file

typo: second it controller -> second is its controller

Why not WebInspector.Size to make it clear that it is not from Web API?

> Source/WebCore/inspector/front-end/View.js:372
> +        this.element.positionAt(undefined, undefined);

Why not reuse Element.measurePreferredSize and simply call this.element.measurePreferredSize() here instead?

I'm adding it into DOMExtension which is compiled outside of inspector. I did not want to invent a namespace for it.

Because we can't operate on View's elements using regular DOM operations.
