        Web Inspector: re-implement xhr breakpoints.
        https://bugs.webkit.org/show_bug.cgi?id=56252

        - restore xhr breakpoints one by one instead of using setAllBrowserBreakpoints
        - store xhr breakpoints in a separate setting
        - move presentation-related code from BreakpointManager to XHRBreakpointsSidebarPane
