[Win32] Remove unnecessary special case for Cursor image data retrieval

A special case for retrieving image data for a cursor directly from the
ImageDataProvider when requesting at 100% was unnecessarily added and
not removed during a refactoring as it was late in the development cycle
and no regression risk wanted to be taken. This now cleans up the
according code and makes the image data always be retrieved from an
image instance instead of the ImageDataProvider directly.
