Gabriel Bourgeois 092bb71bcf Clean up taffy nodes when UI node entities are removed (#5886)
# Objective

Clean up taffy nodes when the associated UI node gets removed. The current UI code will keep the taffy nodes around forever.

## Solution

Use `RemovedComponents<Node>` to iterate over nodes that are no longer valid UI nodes or that have been despawned, and remove them from taffy and the internal hash map.

## Implementation Notes

Do note that using `despawn()` instead of `despawn_recursive()` on a UI node that has children will result in a [warnings spam](https://github.com/bevyengine/bevy/blob/main/crates/bevy_ui/src/flex/mod.rs#L120) since the children will not be part of a proper UI hierarchy anymore.
