qapi/vfio: Rename VfioMigrationState to Qapi*, and drop prefix

QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious.  It's best used with
restraint.

VfioMigrationState has a 'prefix' that overrides the generated
enumeration constants' prefix to QAPI_VFIO_MIGRATION_STATE.

We could simply drop 'prefix', but then the enumeration constants
would look as if they came from kernel header linux/vfio.h.

Rename the type to QapiVfioMigrationState instead, so that 'prefix' is
not needed.
