VR: Partially split the URL bar into elements

The URL bar has always been a single element and texture. Now that the
UI framework has evolved, it's past time to start splitting this up.

This change hacks off the back button, and reduces the catch-all texture
to only the URL origin presentation part of the URL bar.  This could be
further split in the future, but not until we have a linear layout that
can resize children to limit its total size.

Latest thinking here is to highlight the entire half of the URL bar, not just the URL text portion.

The security icon, which is a separate button, should remain separately clickable.

As per discussion with Gordon, there is no current issue with folks knowing to click the URL bar, and highlighting it on hover may not be what we want.

I'm closing this until we have a clear motive to implement this hover effect.

I would suggest filing a new bug at that time.  If not then remove the Test-Complete label so that Test will look at the future changes.
