feat: adding dynamic scenario and object creation tests for CARLA

[abanuelo]

Description

Adding the following three test cases:

1. Car applying throttle increases speed
2. Car applying break will bring the car to a halt
3. Can create all Carla objects. For this third one, there was an error with the BusStop class within model.scenic that needed to be captured. Also note that these tests are automatically skipped as there are memory leak errors with Carla at the moment!

Important!!!!

1. In order to trigger the dynamic scenario tests for CARLA we need to have an environment variable exported called CARLA_ROOT. As part of the simulator CI, this environment variables will be exported as necessary.
2. The pyproject.toml file has been updated such that the only precondition to install the carla pypi package is if we have python version below 3.10. Python 3.11 is giving Carla some problems: Carla fails to install in Python 3.11 venv carla-simulator/carla#7328

Looks good overall -- a few suggestions above.

A few more comments (and one which I've unresolved from before).

Looking good: just a couple last tweaks.
