Tweak the margin value of QOutlineMapper clip rect
The original change was introduced to fix performance regression due to
the increased value of QT_RASTER_COORD_LIMIT. The optimization was done
by clipping anything outside the device rect plus a small margin.
However, setting the margin to a small value caused a regression, where the
rasterization became slightly different from the previous implementation.
Fixes: QTBUG-123054
Pick-to: 6.7 6.5 6.2
