Network Table - Redesign the waterfall popover showing timing data

The current popover just shows a "big graph". Redesign the popover to be more about explanation.

Failure appears to be unrelated to the patch.

r=me, with a couple nits/comments.

> Source/WebInspectorUI/UserInterface/Views/ResourceTimingBreakdownView.css:32
> +    color: gray;

Style: every use of `gray` could be replaced with var(--text-color-gray-medium), but I'll leave it up to you. We should probably just update the variable's value to be gray instead of hsl(0, 0%, 52%).

> Source/WebInspectorUI/UserInterface/Views/ResourceTimingBreakdownView.css:41
> +    padding-left: 5px;

Use -webkit-padding-start for this to be RTL ready.

> Source/WebInspectorUI/UserInterface/Views/ResourceTimingBreakdownView.js:33
> +        console.assert(!fixedWidth || fixedWidth >= 100, "fixedWidth must be at least wide enough for strings");

Nit: assert description should end in a period.

> Source/WebInspectorUI/UserInterface/Views/ResourceTimingBreakdownView.js:56
> +        if (additionalClassName)

I was about to suggest row.classList.add("header", additionalClassName), but learned that `null` and `undefined` get converted to "null" and "undefined" and added as classes!

> Source/WebInspectorUI/UserInterface/Views/ResourceTimingContentView.js:97
> +        breakdownView.updateLayout();

The breakdownView isn't being added to the view hierarchy. This is okay, so long as it never needs to layout again (which seems to be the case, as it implements View.initialLayout but not View.layout). The call to updateLayout does the trick just fine here (a scheduled layout would never run), but thought it was worth mentioning.

Earlier ResourceTimingBreakdownView is used in as popover, which isn't a part of the View hierarchy currently, so updateLayout is required. That said, eventually we should make Popover a view that is a child of the root (document.body).
