[FEATURE] Add genai config prompt template parser

[nmetulev]

Is your feature request related to a problem? Please describe.
We currently maintain prompt templates per model class but that is not scalable. Most models contain a prompt template in the tokenizer_config.json that we could parse and use instead.

Describe the solution you'd like
Create a Jinja parser to parse the templates in the tokenizer_config.json to use as a template for gen ai models
