remove content_origin property from layout (#6155)
Simplified layout algorithm by removing `content_origin`, and instead treating `(0.0, 0.0)` as origin point in every layout object. This change allows overflowing containers that are within auto-layout. The parent element will no longer be moved within the grid cell when its children overflow it.

# Important Notes
When implementing this change, I have found that when object's size was modified without ever touching its position, that change was not being picked up in the "modified children" list, and `on_updated` was never triggered. Because some sprites now are bottom-left aligned, that is now a common case and was reproducible on the auto-layout example scene. I ended up fixing it by introducing another dirty flag for `computed_size` changes. Right now that flag is applied very broadly (on each layout update), but in the future we might make it more precise by actually checking if the size was changed in the process.

I believe that this might also be a fix for #5095, as I cannot reproduce it anymore with those changes.
