Saravanan D 41ffd04644 pci: vfio: Probe migration v2 capabilities ...

Probe VFIO_DEVICE_FEATURE_MIGRATION during VfioCommon::new() and store
the result in a new migration_flags field so later migration phases can
gate state machine transitions.

The probe runs on every instantiation, including snapshot restore,
because migration capability is a property of the host kernel and its
variant driver rather than of any saved VM state.

migration_flags() is added to the internal Vfio trait with a default
implementation that returns Ok(None), meaning not migratable.
VfioDeviceWrapper overrides it to issue the kernel ioctl, while
vfio-user devices keep the default and are always treated as non
migratable.

Allow the VFIO_DEVICE_FEATURE ioctl in the VMM seccomp filter.
