QmlDesigner: Convert the form editor preview image to correct format

Browse Source 
We were passing the image with premultiplied alpha obtained from
QSGRhiLayer::toImage() to be shown in form editor. This corrupts the
colors in with 3D materials having partially transparent colors.
Converting the image to QImage::Format_ARGB32 format fixes the issue.

Fixes: QDS-7474
