Poor CPU and GPU performance is observed when a PlayerInput component with notification behavior set to "Invoke Unity Events" is displayed in the Inspector
How to reproduce:
1. Open the attached “inspector_input_issue” project
2. Open the “SampleScene”
3. Select the “Main Camera” in the Hierarchy window
4. Open Task Manager and navigate to the Performance tab
5. Under the CPU tab, right-click and select “Change graph to → Logical processors”
6. Take note of the usage of each core
7. In the Inspector, change the Behavior field of the PlayerInput component to “Invoke Unity Events”
8. Observe the result in Task Manager
Expected result: The performance of each core is unaffected
Actual result: The utilization of one or more cores is significantly increased
Reproducible in: 1.7.0 (2021.3.39f1, 2022.3.31f1), 1.8.2 (2021.3.39f1, 2022.3.31f1, 6000.0.4f1)
