feat: Audio for macOS (12.0+) guests using Virtio Sound device.

[rockyhetherington]

In macOS 12 (Monterey) Apple added support for Virtio Sound devices. Qemu added the Virtio sound device in 8.2.

Quickemu currently spits out a script for macOS containing the following:

`

-audiodev pa,id=audio0 \

-device intel-hda \

-device hda-micro,audiodev=audio0 \

`

This necessitates disabling SIP and installing VoodooHDA to OpenCore.

Replacing the above code with:

-audio driver=sdl,model=virtio \

Allows both input and output of audio to/from macOS guests with no further modification.

Apple says it added support in macOS 12 (Monterey) but i've only tested and confirmed it working in macOS 15 (Sequoia).

I tried this with Sonoma by doing quickemu --vm macos-sonoma.conf --extra_args "-audio driver=sdl,model=virtio", and it works great. Got audio input and output working.

I confirm this tweak works with macOS 26 (Tahoe) VM too based on macOS 15 (Sequoia) configurations.
