Summary Web Inspector: audit for re-entrancy issues with `initialLayout` and `layout`

It appears that it's possible for re-entrancy issues in the `WI.View` system since the `_didInitialLayout` flag isn't set until _after_ `initialLayout` returns, meaning that if the logic inside `initialLayout` triggers a synchronous `layout` then that second `layout` won't know that it's already in the middle of an `initialLayout`. As an example, showing the `WI.GraphicsOverviewContentView` in `WI.GraphicsTabContentView.prototype.initialLayout` causes the navigation sidebar to be shown, which forces a synchronous `layout` from handling `WI.Sidebar.Event.WidthDidChange`.
