QmlDesigner: Show tooltip preview image for Textures with sourceItem

For non-component sourceItems, the preview shown is simply whatever
image has been stored for form editor for that item.

If the sourceItem is component, the preview image is the same as
sourceItem's preview image, as the form editor image for components
often includes unnecessary empty space.

Note that currently the image stored for form editor doesn't include
child items, so this is not a perfect solution. It is however in line
with what form editor shows for the texture.
