cr-shared-menu usage in MD Settings has now been replaced by a new settings-aciton-menu element which is implemented as a native <dialog>. This addresses several issues that cr-shared-menu has (https://bugs.chromium.org/p/chromium/issues/detail?id=639718).
cr-shared-menu is now used only by MD History. I propose to
1) promote settings-action-menu to a shared cr-action-menu element,
2) Migrate MD History to use it
3) Remove cr-shared-menu completely.
