Add modal dismiss reason / source

[iffa]

Feature Request

Add dismiss reason / source to onDismiss callback / allow passing data via ref.dismiss().

Why it is needed

It would be useful to have the reason the modal is being dismissed in onDismiss, for example if some state needs to be reset when the modal was swiped away VS dismissed programmatically.

Possible implementation
