CVPixelBufferAttributes.AllocateWithIOSurface was initially exposed, but due
to an incorrect merge conflict resolution got removed on macOS
(https://github.com/xamarin/maccore/commit/0feda2d8613a818c2e72c092a4cd8e5b20c5e88e).

CVPixelBufferAttributes.MetalCompatibility was added to iOS first, and then a
year later on macOS, but we never removed the macOS exclusion.

Fixes #24584.
