VR: Get rid of vertical animation on the omnibox

The full spec for omnibox appearing is a fade-in and slide-in from
below, followed by the keyboard fading and rotating up into place.
Because the keyboard doesn't currently animate as expected, we have the
omnibox slide behind an already visible keyboard, which is not good.
This change makes the omnibox simply fade in at its target location.

cmasso@, apologies for the direct request here - could we bypass the 24-hour auto-approve cycle for this change?  It's a trivial change, and will be very helpful for a demonstration later this week if we can get it into 67.

Thanks for the consideration!

Approving the merge as per our offline discussion. Make sure to verify the fix in M67 after merging it.

Tested on a local M-67 checkout cherry-pick, and re-tested by building the tip of the branch after the merge.  Thanks for expediting this, cmasso@!

Verified on build 67.3396.29 beta.  Looks good.
