Sækja Unity 2020.3.10f1

Improvements
- Asset Import: Improved overall performance of FBX files import.
- Asset Import: Improved performance of ASCII FBX files import.
- Graphics: Optimized static batching process, e.g. entering play mode with 30k static batched objects in the editor is faster by two seconds.
- Graphics: Static batching and Mesh.CombineMeshes can handle more vertex formats now, for example Float16 normals or UVs. It also no longer clamps vertex colors to UNorm8 format - if input meshes have higher precision vertex colors, then combined mesh will have high precision colors too. (1274815)
- macOS: Updated xcode project template to use "modern" build system. (1326316)

Changes
- Editor: Updated Collaborate package to allow users to migrate to Plastic.
- Package: Updated the com.unity.purchasing package to version 3.1.0.
