migration: Add thread pool of optional load threads
Some drivers might want to make use of auxiliary helper threads during VM state loading, for example to make sure that their blocking (sync) I/O operations don't block the rest of the migration process. Add a migration core managed thread pool to facilitate this use case. The migration core will wait for these threads to finish before (re)starting the VM at destination.
