* Fix #16007 - colinearity computed using all 3 coordinates

* calib3d(test): estimateAffine3D regression 16007

* Handle det == 0 in findCircle3pts.

Issue 16051 shows a case where findCircle3pts returns NaN for the
center coordinates and radius due to dividing by a determinant of 0. In
this case, the points are colinear, so the longest distance between any
2 points is the diameter of the minimum enclosing circle.
