Add a progress indicator to the VR omnibox

Add a progress indicator to the VR omnibox

The current UX thinking is that the URL indicator (visible transiently
on navigations), and the omnibox, are distict elements that share some
visual similarity.  Mirror the URL indicator's progress-indicating
border on the omnibox, so that there's visible loading progress in the
menu.

Even if we decide that all menu-driven navigations immediately exit the
menu, the user may still pop back into the menu during loading.

Replicate the loading-progress border from the URL indicator on the Omnibox. 
Only one of these shows at a time.
