Make sure M3 users are running VZ emulation and not QEMU

[jandubois]

Current versions of QEMU do not seem to work properly on M3 chips (see lima-vm/lima#1996, https://gitlab.com/qemu-project/qemu/-/issues/1990).

We need to make VZ the default on M3 systems, and also update the settings validator and preferences dialog to prevent M3 users from selecting the QEMU emulation mode.

$ system_profiler -json SPHardwareDataType | jq '.SPHardwareDataType[].chip_type'
"Apple M1 Pro"

I ran into this issue on my new M3 machine and got this error message:

Error: /Applications/Rancher Desktop.app/Contents/Resources/resources/darwin/lima/bin/limactl.ventura exited with code 1

Switching to VZ emulation indeed worked.

Moving to 1.13; for 1.12 it will just be a release-note. Hopefully the upstream issue is resolved in time for 1.13, so we won't need to add diagnostics, but instead update QEMU to a compatible version.
