Handle callbacks into reflex event handlers.

Respect defaults set in ToastProvider toast_options when firing a toast with it's own ToastProps set.

Create new reflex.utils.format.format_queue_events helper method that can be used to take arbitrary eventhandler/eventspec/lambda along with an args spec, and create a callback function for use with rx.call_script-based APIs.

I'm fine with both, let's just go with whatever is more convenient.
