Add a registration_behavior column to AllocationToken (#1695)

This is, as of now, unused but we can use it for b/237683906 and
b/237800445 in the future to allow for special behavior dictated by
allocation tokens rather than having to reserve specific domains.

Note that we enforce a tied domain for ANCHOR_TENANT tokens (because
they should be matched to a domain) but not for BYPASS_TLD_STATE tokens.
