Fix the down-arrow on dropdown menus

Change 319355 has converted gr-button to Lit. gr-dropdown is still on
Polymer, so

  down-arrow="[[downArrow]]"

is interpreted as trying to pass a property (because of [[...]]). That
means Polymer sets the `downArrow` property in <gr-button>. But Lit's
default attribute reflection does not add dashes to the attribute name,
so the property is reflected to `downarrow`.

Fix the problem by specifying the attribute name for the Lit property.
