The current x86_64 emulation try to use the apple-hypervisor as the accelerator which only use 1 cpu on the host machine regardless how much cpu core are assigned.

But changing the accelerator parameter from apple hypervisor to tcg with few more extra parameters which UTM use when emulating improved the emulation performance up to the point docker qemu userspace emulation.

lima-vm#471 imporve qemu emulation of x86_64 on arm64.

This change will use qemu64 cpu for better emulation and add some extra parameters like tcg accel and force multi threading where multiple host threads will be used for vcpus according to qemu documentation. Added few more extra parameters which are used by UTM for better emulation of x86_64

I was about to ask what the "few more extra parameters" are, but it looks like you are working on a PR for this already, so I'll wait until you open that for review! :)
