core: move renderSVGIcon() to qthelper.cpp

The renderIcon() function was used by the thumbnailer to
render SVG-based icons. Move it to the global qthelper.cpp
so that it can also be used by the statistics module.
Add "SVG" to the name to emphasize what it is used for.

For consistency also move the renderSVGIconWidth() function,
which renders to a fixed width, to qthelper.cpp
