Support asynchronous path processing in QQuickPath
Each element in QQuickPath calls processPath() when added or changed
and also other property changes call it. This triggers recreation of
the path multiple times, which can be slow. Instead of direcly
processing the path, allow processing it asynchronously only once
per update.
Task-number: QTBUG-126662
