[Win32] Inline obsolete getScaledImageData() method in Image

The method getScaledImageData() inherited by all image providers is
only has two callers. The calls are difficult to understand as potential
overwrites of the method and included delegation are not obvious. At the
same time, some other code places already contain similar logic inlined.
This change thus inlines the method to ease understanding of the calling
places.
