BufferMetal::AllocNewVersionedBuffer takes longer than expected
SkinnedMeshRenderer creates Metal buffers every frame, taking a considerable amount of frame time.
Issue reported by user in forum: [https://forum.unity.com/threads/unity-creates-metal-buffers-used-inside-the-skinnedmeshrenderer-every-frame-on-ios.1463129/]
Steps:
1. Open TestMetalBuffer in Unity
2. Make a MacOS / iOS build
3. Use XCode Instruments to profile
Expected: BufferMetal::AllocNewVersionedBuffer has little impact on performance
Actual: BufferMetal::AllocNewVersionedBuffer has big impact on performance
