feat: Add tool_invoker_kwargs to Agent

[sjrl]

Related Issues

• fixes Ability to update ToolInvoker max_workers via the agent component #9572

Proposed Changes:

Add tool_invoker_kwargs to the Agent's init method so users can pass additional kwargs to the underlying ToolInvoker like max_workers to control Tool calling parallelism and enable_streaming_callback_passthrough, etc.
