Improvements to Design LTN : Improved shortcut detection

Current behaviour:
When enumerating shortcuts in the LTN tool, it is possible to iterate through all of the potential shortcuts for a specific road segment.
The shortcut detection will respect will turn restrictions which are within a neighbourhood.
The shortcut detection ignore turn restriction at the boundary of a neighbourhood
If there are turn restrictions at the boundary of a neighbourhood, then the shortcut detection does not
Example
LTN-editing-shortcut-detection.mp4
The video shows an example of current behaviour whilst editing Elms Drive - Oxford.
- When there are no turn restrictions, two shortcuts are detected for Elms Drive (one going in either direction)
- With turn restrictions from Marsh Lane, it is not possible to have a shortcut starting at the eastern end of Elms Drive, but this is still detected as a possible shortcut.
Suggested improvement:
The shortcut detection should respect turn restrictions at the boundary of the neighbourhood.
