[devtools] Fix false positive rendering detection in didFiberRender

Improve rendering detection accuracy by adding actual input change verification
for user components that have PerformedWork flag set. This prevents showing
"The parent component rendered" message and highlight updates for components
that didn't actually re-render due to bailouts.

- Add props/state/ref comparison for user components after PerformedWork check
- Restore original props comparison logic for host components
- Fixes issue where bailout components were incorrectly marked as rendered
