AdversarialSimulator should allow caller to specify a particular category of harm for generation

**Is your feature request related to a problem? Please describe.**
My team uses the Azure AI simulator APIs to test the behavior of our generative AI system against harmful inputs. The simulator APIs, best as I can tell, do not give callers the ability to specify the category of harm that it is producing data for.

**Describe the solution you'd like**
The APIs should take additional parameters that allow callers to generate inputs that all map to a specific category of harm, e.g., only violent content, only self-harm content, etc.- or any combination thereof.

**Describe alternatives you've considered**
The only way to generate enough volume of a specific harm is to call the simulator sufficiently many times- but that results in a lot of unnecessary harmful data being generated which we have to then throw away. It'd be much nicer to have the finer-grained control via the API.
