bcachefs: Version table now lists required recovery passes
Now that we've got forward compatibility sorted out, we should be doing
more frequent version upgrades in the future.
To avoid having to run a full fsck for every version upgrade, this
improves the BCH_METADATA_VERSIONS() table to explicitly specify a
bitmask of recovery passes to run when upgrading to or past a given
version.
This means we can also delete PASS_UPGRADE().
