Add Action Meta to onBlur events

[6uzm4n]

In the onChange event there's an Action Meta that exposes the reason the event was called.

Would it be possible to add a similar behavior to the onBlur event? It can also be called due to different reasons: selecting a value, a click outside of the component, a clear, etc.

Right now, detecting the reason it was called is very cumbersome and requires a lot of hacky code, mainly a bunch of refs, that rely on internal behavior that is prone to break with future updates. Having a simple Action Meta parameter in the callback will simplify this a lot.
