Transform Propagation Optimization: Static Subtree Marking (#18589) 
# Objective

- Optimize static scene performance by marking unchanged subtrees.
-
[bef0209](bef0209de1)
fixes #18255 and #18363.
- Closes #18365 
- Includes change from #18321

## Solution

- Mark hierarchy subtrees with dirty bits to avoid transform propagation
where not needed
- This causes a performance regression when spawning many entities, or
when the scene is entirely dynamic.
- This results in massive speedups for largely static scenes.
- In the future we could allow the user to change this behavior, or add
some threshold based on how dynamic the scene is?

## Testing

- Caldera Hotel scene
