Game freezes after command buffer Timeout error - Disable CAMetalDisplayLink by default

Description
CAMetalDisplayLink is causing kIOGPUCommandBufferCallbackErrorTimeout errors. Disabling the CAMetalDisplayLink and using CADisplayLink instead does not cause games to freeze.

IMPORTANT: This issue tracks which fixed versions CAMetalDisplayLink is disabled by default. Check https://issuetracker.unity3d.com/product/unity/issues/guid/UUM-125778 for the actual fix.

IMPORTANT: For previous affected Unity versions you can disable the CAMetalDisplayLink. See https://discussions.unity.com/t/freeze-on-ios-with-metal-display-link/1693201

5. Continue to play the game possibly for more than 30 minutes until the image freezes. A Timeout error is shown in XCode.
