When using TCG emulation for cross-architecture VMs (e.g., x86_64 guest on arm64 host), skip the SSE/AVX CPU feature detection since QEMU emulates these features in software. This fixes macOS guest startup on Apple Silicon Macs.

Fixes #1457

Type of change

  • Bug fix (non-breaking change which fixes an issue)

Checklist:

  • I have performed a self-review of my code
  • I have tested my code in common scenarios and confirmed there are no regressions
