        Scrollbar code cleanup:
        - Remove ScrollbarThemeMac.{mm|h} from the mac sources list, we use
          ScrollbarThemeChromiumMac.{mm|h}
        - Remove USE_WEB_THEME_ENGINE_TO_PAINT_THUMB #define now that switch to
          WebThemeEngine is permanent
        - Fix typo in Linux scrollbar enum name

        No new tests (compiles).
