blockjob: introduce .drain callback for jobs

This is required to decouple block jobs from running in an
AioContext.  With multiqueue block devices, a BlockDriverState
does not really belong to a single AioContext.

The solution is to first wait until all I/O operations are
complete; then loop in the main thread for the block job to
complete entirely.
