commit 16278c75a09262bfc2b1e230730f79ec5a4d4918

Do not reset initial scroll position in LazyColumn/Row when items are loaded asynchronously

If the initial scroll position(or restored scroll position) is not 0 this value will be immediately overridden by 0 if there were no items yet provided for LazyColumn/Row.
It is easily reproducible with Paging where we start loading asynchronously and there is always a first frame when we don't have any items.

Fixes: 177245496
Test: new tests for LazyColumn and LazyRow

I think this issue still exists. The fix could break easily when you add a header item to LazyColumn.

Yes, we basically just changed the default behavior for the empty case for now. Please track this bug b/179397301 for the following work in this space.

Also, the itemCount always started from 0 when navigated back. I can't identify whether it is really empty or just a temporary state. Especially if I need to show an empty UI, it will flash shortly then display the paging data.

My workaround currently is to keep `LazyPagingItems` object in `ViewModel`, so that `itemCount` and other state will be the same when navigated back.
