Fixes#4817

BREAKING: `MdMenu.prototype.anchor` now only accepts a string which will querySelector the rootNode of the menu. The method now to anchor to an element reference is to set `MdMenu.prototype.anchorElement`. This matches the `popover` anchoring proposal more closely, but that proposal may not pass in favor of a CSS approach.
