Fix a number of small issues with the SUI (#12287)

## Summary of the Pull Request
Fix various things from the recent SUI changes

- The Appearance/Advanced toggle buttons now have a max width
- We don't need `Profiles.cpp` anymore
- The `Elevate` setting is now back in the SUI
- There is no longer an alignment difference between non-expander settings and expander settings
- Expander settings no longer require hitting `Tab` twice to get to them
