Restore disabled dragging and context menu for Bookmarks Bar on Windows

Previously it was enough to not add 'drag' to the bookmarks bar on Windows, but now that it is added at a higher level in the DOM (so that dragging works in the margin between the bars) via #10512, we have to explicitly set it to 'no-drag' on each child.

Fix #11728
