Add new CPU flags for HyperV: hv_vapic for virtual APIC support hv_spinlocks for spinlock support

Is the Microsoft documentation for this feature use hex values?
It uses 0xFFFFFFFF as the special value meaning "no retries" [1] QEMU uses hex values too, but it parses the number with strtoul and base 0 (just as we do), meaning decimal and octal values are allowed too.
</hyperv> </features>
results in the following QEMU command line: qemu -cpu <cpu_model>,hv_vapic,hv_spinlocks=0xffff
