vfio: Remove 'vfio-platform'

The VFIO_PLATFORM device type has been deprecated in the QEMU 10.0
timeframe. All dependent devices have been removed. Now remove the
core vfio platform framework.

Rename VFIO_DEVICE_TYPE_PLATFORM enum to VFIO_DEVICE_TYPE_UNUSED to
maintain the same index for the CCW and AP VFIO device types.
