qemu: Introduce QEMU_DOMAIN_JOB_STATS_TYPE_SAVEDUMP

Browse Source 
Add a TYPE_SAVEDUMP so that when coalescing stats for a save or
dump we don't needlessly try to get the mirror stats for a migration.
Other conditions can still use MIGRATION and SAVEDUMP interchangably
including usage of the @migStats field to fetch/store the data.
