kunit: enable hardware acceleration when available
Use KVM or HVF if supported by the QEMU binary and available on the
system.
This produces a nice improvement on my Apple M3 Pro running macOS 14.7:
Before:
./tools/testing/kunit/kunit.py exec --arch arm64
[HH:MM:SS] Elapsed time: 10.145s
After:
./tools/testing/kunit/kunit.py exec --arch arm64
[HH:MM:SS] Elapsed time: 1.773s
