Raster painting: fix dashing for separate lines
When drawing multiple distinct (unconnected) lines (e.g. from
QPainter::drawLines() or a QPainterPath with alternating
movetos/linetos), the dash pattern should not continue from one to the
next, as it should when drawing a connected line (e.g. polyline).
Both the cosmetic stroker and the full stroker does it right, but the
fast rasterizing codepath got it wrong.
Fixes: QTBUG-83048
