Animation: Fix case where QEasingCurve::valueForProgress returns nan
Previously, we would divide by zero in BezierEase::findTForX if factorT3
was zero when solving the cubic equation.
This change fixes the problem by adding solutions for the special cases
where the cubic equation can be reduced to a quadratic or linear
equation.
This change also adds tests that cover cases where the equation becomes
quadratic, linear or invalid.
Task-number: QTBUG-67061
