Improve default crops on tablet

The fix is pretty targeted: only for tablets (not foldable), only when
we're trying to figure out the crop on portrait.

This only applies when there are no suggested crops: on Pixel it will
mostly affect the default wallpaper.

The specs are:
 - first compute the crop on landscape (left-aligned)
 - if there is parallax, compute the crop without parallax
 - the crop on portrait is the largest crop with the same center as the
   computed crop on landscape.
 - add parallax to the portrait crop so that its virtual right-end (or
   left-end if RTL) is the same as the crop on landscape

I think this should work well on all cases (even if the full image is
not landscape).
