allow ACL policies to be associated with workload identity (#14140)
The original design for workload identities and ACLs allows for operators to
extend the automatic capabilities of a workload by using a specially-named
policy. This has shown to be potentially unsafe because of naming collisions, so
instead we'll allow operators to explicitly attach a policy to a workload
identity.

This changeset adds workload identity fields to ACL policy objects and threads
that all the way down to the command line. It also a new secondary index to the
ACL policy table on namespace and job so that claim resolution can efficiently
query for related policies.
