        Web Inspector: TabBar redesign: remove top-level search field and pin the Search tab

        * Localizations/en.lproj/localizedStrings.js:

        * UserInterface/Base/Main.js:
        (WI.contentLoaded):
        Create Search UI based on experimental setting. When the new TabBar is
        enabled, the Search tab is a pinned tab. Since it is also saveable, it
        needs to be added to the TabBrowser (the browser adds the item to the bar).

        When restoring saved tabs, make an additional check to prevent a tab
        from being added twice. This can occur now that the Search tab is pinned.

        * UserInterface/Images/Search.svg:
        Update art to better match Safari/macOS. Slightly increase the radius of
        the lens, and shorten the length of the handle.

        * UserInterface/Views/GoToLineDialog.css:
        (.go-to-line-dialog > div::before):
        Update styles for new Search icon.

        * UserInterface/Views/LegacyTabBar.js:
        (WI.LegacyTabBar.prototype.get saveableTabCount):
        Backported new TabBar method which is called by TabBrowser.

        * UserInterface/Views/OpenResourceDialog.css:
        (.open-resource-dialog > .field::before):
        Update styles for new Search icon.

        * UserInterface/Views/PinnedTabBarItem.js:
        (WI.PinnedTabBarItem.prototype.fromTabInfo):
        Match GeneralTabBarItem.fromTabInfo.

        * UserInterface/Views/SearchTabContentView.js:
        (WI.SearchTabContentView):
        (WI.SearchTabContentView.tabInfo):
        New image (magnifying glass without border) when new TabBar is enabled.

        * UserInterface/Views/SettingsTabContentView.js:
        (WI.SettingsTabContentView):

        * UserInterface/Views/TabBar.js:
        (WI.TabBar):
        Move creation of the Settings item out of TabBar. The TabBar should
        only be concerned with managing tabs.

        (WI.TabBar.prototype.get saveableTabCount):
        (WI.TabBar.prototype._handleContextMenu):
        (WI.TabBar.prototype.get normalNonEphemeralTabCount): Deleted.
        Now that the Search tab is pinned, there aren't any normal tabs that
        are also ephemeral. For the LegacyTabBar, both the Search and New Tab
        tabs are still in this category.

        * UserInterface/Views/TabBrowser.js:
        (WI.TabBrowser.prototype.addTabForContentView):
        (WI.TabBrowser.prototype.closeTabForContentView):
        (WI.TabBrowser.prototype._tabBarItemSelected):
        (WI.TabBrowser._tabBarItemRemoved):
        Recent tab list should be validated against the list of saveable tabs,
        since the Search tab is no longer a normal tab (a GeneralTabBarItem),
        but is still persisted across Inspector sessions.

        CSSProperty models were updated with a 250ms delay. Quickly adding a blank property after modifying
        an existing property could result in outdated values being shown.

        This patch removes the 250ms delay.

        <rdar://problem/35431882>

        Reviewed by Joseph Pecoraro.

        Data corruption used to happen because CSSStyleDeclaration.prototype.text didn't
        update synchronously. Making two or more quick changes resulted in corrupted data.

        Imagine we modify a CSS value 3 times:

        Front-end:  (1)-(2)---(3)
        Back-end:          (1)-----(2)-(3)

        The first response from the backend could happen after the 2nd edit. In this patch,
        CSSStyleDeclaration is locked when its view is being edited.

        To correctly display invalid and overridden properties, the backend is allowed to update
        CSSStyleDeclaration and CSSProperty when they're locked if the text from the backend
        matches the model's text. This should happen when the backend is caught up with the
        front-end changes.

        Reviewed by Joseph Pecoraro.

        Add a new method, fetchProperties, which async fetches an arbitrary list of properties
        from a RemoteObject. This is intended for writing tests and other quick evaluations,
        so it has some behaviors that are suitable in these situations:
        - If the evaluation throws an exception, the result will reject with that exception.
        - If there is a protocol error for some reason, the result will reject with an exception.
        - Non-string and non-number keys cause an exception, as this is probably not intended.
        - Does not accept a callback, returns a promise only. New code should use async.

        For full fidelity introspection of property descriptors, clients should use the existing
        getOwnPropertyDescriptor[s] class of methods.

        (WI.RemoteObject.prototype.async.fetchProperties): Added.
