Retrieve the stack_index from Node in extract_ui_material_nodes instead of walking UiStack (#15104)

Browse source 
# Objective

 `ExtractedUiMaterialNode` is still walking the whole `UiStack`. 

more info: https://github.com/bevyengine/bevy/pull/9853

## Solution

Retrieve the `stack_index` from the `Node` component instead.
Also changed the `stack_index` field of `ExtractedUiMaterialNode` to
`u32`.
