Follow up CLs will update CS to generate blocked reason from bpf map
instead of asking NPMS.
However, one issue is NPMS set PENALTY_BOX for
BLOCKED_METERED_REASON_USER_RESTRICTED and
BLOCKED_METERED_REASON_ADMIN_DISABLED without telling the reason.
So, CS can not know the reason of PENALTY_BOX.
This CL add new firewall chain and match to distinguish reasons.
NPMS must call setUidFirewallRule with
FIREWALL_CHAIN_METERED_DENY_USER or FIREWALL_CHAIN_METERED_DENY_ADMIN
based on the reason so that CS can know the reason of restriction.
