 		f6aa19709e feat(prebuilt): Add dynamic model to create_react_agent (#5651) 
This PR allows a developer to change the model configuration at run time based on context. This includes that list of tools available to the model to call.

```python
def create_react_agent(
    model: Union[
        str, 
	LanguageModelLike,
        Callable[[SateLike, Runtime...], BaseChatModel], # <--- New
    ],
    tools: Union[
      Sequence[Union[BaseTool, Callable, dict[str, Any]]], ToolNode]
    ],
    *,
....


llm = init_chat_model(...)

def prepare_model(state, runtime):
   selected_tool_names = func(state, context)
   return llm.bind(tools=selected_tool_names)

create_react_agent(
  prepare_model,
  tools=all_known_tools
)
```

## Semantics

1. `tools` = are the known tools, used to configure ToolNode and will
configure:
    1. model provided as string
    2. model provided as BaseChatModel (if it has no tools bound to it)
2. If a user provides a dynamic model (callable), the user is
responsible for binding tools


Alternative considered:

1. Passing `Callable[[SateLike, Config...], list[BaseTool]]` to tools
2. Passing `Callable[[SateLike, Config...], list[str]]` to a tool
selector

Both have the issue that there's non obvious interplay between tool
selection and dynamic models. (i.e., if we want to introduce dynamic
models at in the future, the API will become tricky to explain)
