[UI Toolkit] Update Layout CPU Usage is huge even when only one element is changed
How to reproduce:
1. Open the user's attached "SlowLayout" project
2. Enter the Play Mode in the "SampleScene" Scene
3. Open the "Window -> Analysis -> Profiler" window from the menu
4. Search for the "Update Layout" Overview under the "CPU Usage"
Expected result: Only the Text element layout is changed. Thus, "Update Layout" CPU Usage is ~1 ms
Actual result: The "Update Layout" CPU Usage is ~30 ms
Reproducible with: Built-In (2021.2.13f1, 2022.1.0b9, 2022.2.0a5)
Couldn't test with: 2019.4.36f1 (UI Toolkit Package is unavailable), 1.0.0-preview.18 (2020.3.30f1) (user project isn't compatible, errors are thrown)
