Added native image handle provider support in pixmaps on openvg.

QNativeImageHandleProvider is a thin interface consisting of get()
and release() functions. Pixmaps constructed with such a provider
will call these functions to acquire and release a native handle,
e.g. a CFbsBitmap or RSgImage pointer in case of Symbian. The behavior
is largely similar to constructing pixmaps via fromSymbianCFbsBitmap
or fromSymbianRSgImage, with the exception of pixmap hibernation:
release() (and subsequently get()) is guaranteed to be called also
in case of hibernation, allowing more fine-grained tracking of
the usage and lifetime of image data.
