Guard against numerical overflow when processing QPainterPaths
Many operations on and with QPainterPaths do calculations on the path
coordinates, e.g. computing the distance between points, which may cause
numerical overflow for extreme coordinate values. This patch
introduces a limit on the coordinate values and extends the previous
check against nan/inf coordinates to also check against out of range
coordinates.
Fixes: QTBUG-75574
