fix(quickemu): enable vmware TSC and disable ACPI PCI hotplug for macOS 

- Pass vmware-cpuid-freq=on to -cpu on Intel hosts to enable VMware TSC
  frequency reporting and improve macOS timing
- Add ICH9-LPC flag to disable ACPI PCI hotplug bridge support to avoid
  macOS PCI hotplug issues (required for QEMU 6.1+)
