Btrfs-progs: Introduce metadump_v2
The METADUMP super flag makes us skip doing the chunk tree reading which isn't
helpful for the new restore since we have a valid chunk tree. But we still want
to have a way for the kernel to know that this is a metadump restore so it
doesn't do things like verify data checksums. We also want to skip some of the
device extent checks in fsck since those will obviously not match. Thanks,
