SystemInfo.get_graphicsDeviceName() is generating garbage GC Alloc when using Metal graphics API
Reproduction steps:
1. Open the attached "test_disc.zip" project
2. Open the "Assets/OutdoorsScene.unity" Scene
3. Open the Profiler ("Window -> Analysis -> Profiler")
4. In the Profiler, turn on Deep Profile
5. Enter the Play Mode
6. After a few seconds, pause the Play Mode
7. In the Profiler, select the last frame (or second to last)
8. Search for "SystemInfo.get_graphicsDeviceName()" method
9. Observe the method's GC Alloc value
Expected result: The value is 0 B
Actual result: The value is around 50 B
