Add TriangleFan pipeline topology
Triangle fan drawing is only supported on some platforms. The feature
flag QRhi::TriangleFanTopology is set accordingly.
In general, TriangleStrip topology will be more efficient on most GPUs.
However, if polygon data is already stored as triangle fans, the CPU
savings may be more significant.
