QmlDesigner: Unify the background of 3D preview images

Added 3D checkerboard floor on all 3D previews.
Since shadows generally look bad for arbitrary 3D scenes, and would
mostly be obscured by the model itself as we want the light mostly
from the front, removed shadows also from the material preview to unify
the previews.

Qt5 had issues rendering the 3D floor texture, so used a static image
there, as Qt5 only generates previews of one size.

Fixes: QDS-7078
