tests/qtest: migration: Add migrate_incoming_qmp helper 

file-based migration requires the target to initiate its migration after
the source has finished writing out the data in the file. Currently
there's no easy way to initiate 'migrate-incoming', allow this by
introducing migrate_incoming_qmp helper, similarly to migrate_qmp.

Also make sure migration events are enabled and wait for the incoming
migration to start before returning. This avoid a race when querying
the migration status too soon after issuing the command.
