ANAVHEOBA afea2af139 net: reduce log level for PCP/NAT-PMP NOT_AUTHORIZED failures ...

Users running on home networks with routers that don't support PCP (Port
Control Protocol) or NAT-PMP port mapping receive frequent warning-level
log messages every few minutes:

  "pcp: Mapping failed with result NOT_AUTHORIZED (code 2)"

This is expected behavior for many consumer routers that have PCP
disabled by default, not an actionable error.

Add explicit constants for the NOT_AUTHORIZED result code (value 2)
for both NAT-PMP and PCP protocols. Log the first NOT_AUTHORIZED
failure at warning level for visibility, then downgrade subsequent
occurrences to LogDebug to avoid log noise. Other failure types
continue to warn unconditionally.

Fixes #34114
