clang-format: Improve linebreaking and indentation for ObjC calls.

Before:
  popup_wdow_.reset([[RenderWidgetPopupWindow alloc]
      iniithContentRect:
          NSMakRet(origin_global.x, origin_global.y, pos.width(), pos.height())
                syeMask:NSBorderlessWindowMask
                  bking:NSBackingStoreBuffered
                    der:NO]);
  [self param:function( //
      parameter)]

After:
  popup_wdow_.reset([[RenderWidgetPopupWindow alloc]
      iniithContentRect:NSMakRet(origin_global.x, origin_global.y, pos.width(),
                                 pos.height())
                syeMask:NSBorderlessWindowMask
                  bking:NSBackingStoreBuffered
                    der:NO]);
  [self param:function( //
                  parameter)]
