Robert Swain 54d2e86afc bevy_transform: Use Changed in the query for much faster transform_propagate_system (#4180) 
# Objective

- Improve transform propagation performance

## Solution

- Use `Changed<Transform>` as part of the `root_query` and `transform_query` to avoid the indirection of having to look up the `Entity` in the `changed_transform_query`
- Get rid of the `changed_transform_query` entirely
- `transform_propagate_system` execution time for `many_cubes -- sphere` dropped from 1.07ms to 0.159ms, an 85% reduction for this system. Frame rate increased from ~42fps to ~44fps
