Add new reserved domain creation from allocation tokens mechanism

Note that this gets rid of anchor tenant codes in reserved lists (yay!), which
are no longer valid.  They have to come from allocation tokens now.

This removes support for LRP from domain application create flow (that's fine,
we never used it and I'm going to delete all of LRP later).  It also uses
allocation tokens from EPP authcodes as a fallback, for now, but that will be
removed later once we switch fully to the allocation token mechanism.

This doesn't yet allow registration of RESERVED_FOR_SPECIFIC_USE domains using
the allocation token extension; that will come in the next CL.  Ditto for
showing these reserved domains as available on domain checks when the allocation
token is specified.
