[macOS][Windows] Repaint events take a very long time when opening the Inspector/changing values/navigating

Metal

-

How to reproduce:
1. Open the attached project's Scene labeled "OpenMe.Heavy"
2. Move the mouse around
3. Click on the "Main Camera" to open the Inspector
4. Try changing values in the Inspector
5. Observe the delay between actions

Expected result: Performance is similar to a Windows Editor
Actual result: There's a considerable amount of delay compared to Windows (10 times slower)

Reproducible with: 2019.4.28f1, 2020.3.13f1, 2021.1.13f1, 2021.2.0b1

Note:
- Noticeable on a Scene with a lot of GameObjects
- Affected versions have less garbage allocated but longer CPU delays
- Not reproducible versions have more garbage allocated (about 3 times) but shorter CPU delays (2-3 times)
