gpui: Fix list scroll events being reverted by pending scroll (#59002)

This PR fixes some cases where scrolling is choppy due to a user
inputting a scroll event while a list state is going through a
remeasure. Currently, the list state would ignore the user's scroll and
fall back to the pending scroll position, this PR fixes this by rebasing
the pending scroll onto the user's new scroll position.
