Update bind_tools to construct a dict that matches VertexAI Tool proto and bind that to the model
Update bind_tools to accept FunctionDeclaration and Vertex Tool directly
Update bind_tools to accept a tool_choice param for easier tool_config setting
Refactor generate, agenerate, stream, astream to reuse gemini param setting and response parsing
