Graphic acceleration in Apple backend for macOS VM on Apple Silicon Mac

**Update Nov 08 2023**

Maybe partial graphic acceleration support since 4.4.x?

Go to the [comment](https://github.com/utmapp/UTM/issues/5785#issuecomment-1793672595) for details.

**Describe the issue**

I created a macOS 13.6 VM guest with Apple backend on my M1 machine.
I had some troubles that some apps failed to launch inside the guest and someone told me that it was due to lack of graphic acceleration.
I searched the VM configuration panel of UTM and the official documentation but find nothing talking about this.
Therefore I want know if there is graphic acceleration support.

**Configuration**

* UTM Version: 4.3.5
* macOS Version: 13.6
* Mac Chip (Intel, M1, ...): M1
