    `FindBrowserWithWebContents` renamed upstream

    This is a simple function rename with no other effects.

        Rename FindBrowserWithWebContents to FindBrowserWithTab

        "WebContents" hasn't been synonymous with "tab" since the content
        split. It's confusing to have a function that says it finds a browser
        by "web contents" yet only looks at the tabs.

        Rename the function so that its name accurately reflects its function.

        Bug: none
