i386/hvf: Adds support for INVTSC cpuid bit
This patch adds the INVTSC bit to the Hypervisor.framework accelerator's CPUID bit passthrough allow-list. Previously, specifying +invtsc in the CPU configuration would fail with the following warning despite the host CPU advertising the feature: qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000007H:EDX.invtsc [bit 8] x86 macOS itself relies on a fixed rate TSC for its own Mach absolute time timestamp mechanism, so there's no reason we can't enable this bit for guests. When the feature is enabled, a migration blocker is installed.
