hw/acpi: Update ACPI `_STA` method with QOM vCPU ACPI Hotplug states
Reflect the QOM vCPUs ACPI CPU hotplug states in the `_STA.Present` and
and `_STA.Enabled` bits when the guest kernel evaluates the ACPI
`_STA` method during initialization, as well as when vCPUs are
hot-plugged or hot-unplugged. If the CPU is present then the its
`enabled` status can be fetched using architecture-specific code [1].
Reference:
[1] Example implementation of architecture-specific hook to fetch CPU
`enabled status
