bcachefs: bkey_ops.min_val_size
This adds a new field to bkey_ops for the minimum size of the value,
which standardizes that check and also enforces the new rule (previously
done somewhat ad-hoc) that we can extend value types by adding new
fields on to the end.
To make that work we do _not_ initialize min_val_size with sizeof,
instead we initialize it to the size of the first version of those
values.
