[Feature]: Move examples to a separate repository

[erikbosch]

Description

We have some examples in this repository, but to run/use them you typically need to clone https://github.com/eclipse-velocitas/vehicle-app-cpp-template and copy them to the app folder of the project. That gives sort of a circular dependency and makes it difficult to test the examples

Suggested Solution

Move the examples to a separate repository, which can have dev-dependencies to both template-repo and this repo. Then you could as part of CI test that they work using the template and the sdk.

Alternatives

• Keep examples untested, as today
