We already have the button hiding from the [show-menu] attribute in CSS, but
switching to a dom-if is a good idea.

You can delete the `:host(:not([show-menu])) #menuButton` block above, use
[[showMenu]] in this dom-if, and remove the `reflectToAttribute` from showMenu
in cr_toolbar.js

Acknowledged.
md_history/ depended on [show-menu] but it mirrored that state into [has-drawer]
(which is also reflected), so I just had to tweak the selector to get the same
result.  Done.

Cool, I was just about to implement something similar for the (i) button in
history.
