A Z or M dimension is added to ``point`` if one of the points in the list
``points`` contains Z or M value.
This method is equivalent to successively calling Z and M but avoiding
looping twice over the set of points.
:param geom: geometry in which a M point is searched.
:param point: The point to update with Z or M dimension and value.
:return: ``True`` if the point is updated, ``False`` otherwise

This method does not copy the z or m value of the coordinate from the
points whose z or m value is closest to the original x/y point, but only the first one found.
