blkdebug: Implement bdrv_co_preadv/pwritev/flush

This enables byte granularity requests for blkdebug, and at the same
time gets us rid of another user of the BDS-level AIO emulation.

Note that unless align=512 is specified, this can behave subtly
different from the old behaviour because bdrv_co_preadv/pwritev don't
have to perform alignment adjustments any more.
