New example: City Builder

[D8H]

This example shows how to evaluate distance by roads to define rules for city builders.

This example use these extensions:

• an updated Linked Object Tool that allows to get the distance and combine several search to build complex rules (Updated extension: distance evaluation for Linked Object Tools GDevelop-extensions#144).
• the Isometry Helper to snap objects on a grid (New Extension: Isometry Helper GDevelop-extensions#102)
• the Mouse Movement without any change (New extension: Mouse movement conditions GDevelop-extensions#123)

The original discussion: 4ian/GDevelop#2638
