OSX specific: Fixed darker colors of objects inside multi-material gizmo on macOS running on Arm64 CPU.

Browse source 
For Apple's on Arm CPU computed triangle normals inside fragment shader using dFdx and dFdy has the opposite direction. Because of this, objects had darker colors inside the multi-material gizmo.
Based on https://stackoverflow.com/a/66206648, the similar behavior was also spotted on some other devices with Arm CPU.
