Move MACsec offload API and ethtool feature tests from tools/testing/selftests/drivers/net/netdevsim/macsec-offload.sh to tools/testing/selftests/drivers/net/macsec.py using the NetDrvEnv framework so tests can run against both netdevsim (default) and real hardware (NETIF=ethX). As some real hardware requires MACsec to use encryption, add that to the tests.
Netdevsim-specific limit checks (max SecY, max RX SC) were moved into separate test cases to avoid failures on real hardware.
