Get the thumbnail aspect ratio from the cached value

This CL updates the two acquired thumbnail aspect ratio usages to use
the cached value. Both of the usages has been gated by
TabUiFeatureUtilities#isTabThumbnailAspectRatioNotOne which is already
using the cached valued.

Note: this CL is split from crrev.com/c/2427345
