QEasingCurve: add some strategic std::move()

Move instead of copy the bezierCurves and tcbPoints
containers when updating 'config' in setType_helper().

In Qt 5, we still have the unsharable container
issue which causes code for deep copies to be
emitted for most copy operations.

A move is always just re-seating a pointer.
