tools: ynl-gen: generate nested array policies 



This patch adds support for NLA_POLICY_NESTED_ARRAY() policies.

Example spec (from future wireguard.yaml):
-
  name: wgpeer
  attributes:
    -
      name: allowedips
      type: indexed-array
      sub-type: nest
      nested-attributes: wgallowedip

yields NLA_POLICY_NESTED_ARRAY(wireguard_wgallowedip_nl_policy).

This doesn't change any currently generated code, as it isn't
used in any specs currently used for generating code.
