target/i386/hvf: add vmware-cpuid-freq cpu feature
For `-accel hvf` cpu_x86_cpuid() is wrapped with hvf_cpu_x86_cpuid() to
add paravirtualization cpuid leaf 0x40000010
https://lkml.org/lkml/2008/10/1/246
Leaf 0x40000010, Timing Information:
EAX: (Virtual) TSC frequency in kHz.
EBX: (Virtual) Bus (local apic timer) frequency in kHz.
ECX, EDX: RESERVED (Per above, reserved fields are set to zero).
On macOS TSC and APIC Bus frequencies can be readed by sysctl call with
names `machdep.tsc.frequency` and `hw.busfrequency`
This options is required for Darwin-XNU guest to be synchronized with
host
Leaf 0x40000000 not exposes HVF leaving hypervisor signature empty
