Geometry_Engine: Restore coherency and add tolerance to PointAtParameter methods

#### Broken rules:

Some of `PointAtParameter` methods allow the parameter to be outside of 0 to 1 domain while others in those cases return nulls.
Also `Polyline` and `PolyCurve` methods has hard coded check to return endpoint while parameter is equal 1 (to avoid computational errors). This could be replaced by using tolerance.

#### Suggestions to restore compliance:

- Make all methods prohibit input parameter from being outside of the 0 to 1 domain. Ensure that 0 means the startpoint and 1 the endpoint of the curve.
- Add proper descriptions and return null with logging an error when parameter is outside the 0 to 1 domain.

#### Additional notes:
- Circles and other closed curves are discussable.
- ~~In case of Nurbs parameter could be scaled to meet the requirement from first suggestion.~~
