Changed QPixmap VG backend to use CFbsBitmap on Symbian.

Similarly to QS60PixmapData, that is used on raster, QVGPixmapData
is also backed by a CFbsBitmap from now on (at least when it makes
sense to do so). This allows copy-less bitmap handle duplication in
from- and toSymbianCFbsBitmap() in case of certain image formats,
reduces local heap usage and improves performance with the s60 style
due to a reduced number of pixel data copies.
