fix(cdk-experimental/menu): ensure context menu is closed out with other menu elements on page

Fixes an issue which prevents an open context menu from closing out if clicked on a menu bar
element or on an inline menu. Further fixes an issue where opening a context menu does not close
out any open menu.
