Add a Test Cluster in order to validate the generation/implementation of the Data Model

[vivien-apple]

Problem

Often while adding some features to ZAP or to into the Ember stack I need to set up a kind of "fake" cluster that uses what needs to be implemented.
Also, it may be useful to have a cluster written just to check that either the ZCL or the IM messages dispatching works properly.

This PR add a Test Cluster. This cluster contains a few commands only, and a list of attributes that are supported by the stack.

Summary of Changes

• Add a Test Cluster zcl definition (first commit)
• Add a server implementation for the Test Cluster (second commit)
• Activate this cluster into multiples .zap files (third commit)
• Use this Test Cluster into the Darwin CI (fourth commit)
• Update gen/ folders (last commit)
