High polling rate mice are causing performance issues (windows, editor)
Reproduction steps:
1. Open users attached project (note this project doesn't use the new input system, but the issue manifests in the new input system too. See ISX-1506)
2. Press the "Stats" button on the Game View window
3. Enter the Play Mode
4. Move the mouse rapidly over the Editor
5. Observe the Frame rate in the Stats window
Expected result: Frame rate is stable
Actual result: Frame rate is jumping from ~400 to ~200
Reproducible with: 2019.4.38f1, 2020.3.33f1, 2021.3.0f1, 2022.1.0b16, 2022.2.0a11
Notes:
-reproduced with Razer Viper
-frame rate drop is more apparent with a higher polling rate (1000hz)
-in 2019.4, the performance drop is not as major, but still visible
-reproduces in any project

Still present with 2021.3.8f1 LTS. Almost unusable at 1000 Hz. It's better with 125 Hz but it still have mini lag spikes every now and then. This issue should be a priority to fix on LTS versions. It really impacts the work.
Reproducible with: Corsair Harpoon mouse -

Can also confirm for 2021.3.5f1 with Logitech G502 at 1000Hz. Build is running smoothly if mouse is stationary, but any rapid movement causes lagspikes in the "Others" section of profiler. In Editor, it goes to EditorLoop.
