Construct a point with the provided initial coordinate values.

|
If ``wkbType`` is set to `QgsWkbTypes.Point`, `QgsWkbTypes.PointZ`, `QgsWkbTypes.PointM` or `QgsWkbTypes.PointZM`
|
|
the type will be set accordingly. If it is left to the default `QgsWkbTypes.Unknown`, the type will be set
|
|
based on the following rules:
|
|
|
|
- If only x and y are specified, the type will be a 2D point.
|
|
- If any or both of the Z and M are specified, the appropriate type will be created.
