Adds sampling parameters to the Prompt API. These control how tokens are sampled from the model, giving developers control over the "creativeness" or "randomness" of the output. Additionally, it adds attributes to the LanguageModel instance to read the set values, as well as a static LanguageModel function to get the default and max values of these parameters. The first implementation adds `temperature` and `topK` parameters.
