[Feature Request] Support scroll adjusted translate

Hello,

In the legacy dnd-kit events, there was a `delta` field representing the scroll adjusted translate, whose value equals `viewport-based delta + scroll delta`. However the new version is missing this feature — currently there is only a `transform` field representing the viewport-based delta.

I'm requesting that this functionality be ported to the new version.

I'm working a PR to port this feature referencing the legacy implementation.
