fdo#74702 New abstract function UsePolyPolygonForComplexGradient()

A new protected abstract function has been introduced only for
complex gradients. As it stands, we currently need to work out if
we should use a PolyPolygon or a Polygon because, as the comments
say:

// Determine if we output via Polygon or PolyPolygon
// For all rasteroperations other then Overpaint always use
// PolyPolygon, as we will get wrong results if we output multiple
// times on top of each other.
// Also for printers always use PolyPolygon, as not all printers
// can print polygons on top of each other.

Interestingly, the next line is either wrong or expressed badly,
because the check uses PolyPolygons when a VirtualDevice is in use:

// Also virtual devices are excluded, as some drivers are too slow.

Therefore, I've removed that comment as it seems rather misleading.
