Add optimized path for QML ShapePath
Improve performance of QML ShapePath, especially with more complex
animating paths. Testing revealed that considerable amount of time
is used for calculating QPainterPath::length(). QML ShapePath
doesn't support QQuickPathAttribute or QQuickPathPercent, so it
can have a fast-path for creating the path without calculating
length or attributes.
This gave heavy bezier lines rendering test ~7x performance boost.
