Summary: Merge toolbar items and dashboard into TabBar. This should go behind an experimental feature flag until we've lived on it a while. The new bar will include (left to right): - Close (docked only) - Tabs (Elements, Network, etc) - Tab picker (when tabs hidden/collapsed) - Console messages mini-dashboard - Inspect element - Search - Dock/undock - Settings Some items previously in the dashboard/toolbar are not included in the redesign. The Reload and Download Web Archive buttons are redundant, as long as we have a way to surface the Reload Ignoring Cache shortcut. Resource/timing dashboard items can be relocated to the Network tab as a status element. That leaves the Pause Location dashboard item. This is a useful top-level notification, and it would be good to indicate paused state state somehow in the new design.

This bug has been re-focused on the top-level dashboard UI only. Other buttons (close, docking, inspect element) are covered by their own bugs: <https://webkit.org/b/182413> Web Inspector: TabBar redesign: add close and docking buttons to the TabBar <https://webkit.org/b/183674> Web Inspector: TabBar redesign: add Inspect element button
