[Metal] Using Models with Blend Shapes causes the Skinning to happen on the CPU instead of the GPU

Metal

-

To reproduce:

1. Download attached project "blend-shapes.zip" and open in Unity
2. Open "SampleScene" scene
3. Make sure the current target is Standalone or iOS
4. Make sure GPU Skinning is enabled in PlayerSettings
5. Open Unity Profiler
6. Enter to Play Mode
7. Record a few frames, then Pause/Stop PlayMode
8. In the CPU Profiler, click on a frame
9. Switch to Timeline view

Expected results: MeshSkinning.Skin marker should not be visible
Actual results: MeshSkinning.Skin appears on Mac

Notes:
- This issue only appears on Metal Graphics API
- The Correct behavior would be if You see on Profiler MeshSkinning.SkinOnGPU
- The Project and Profiler results are attached in the Comments section
