[PATCH 4/7] wifi: mt76: connac: add NAN connection type

[Sean Wang <sean.wang@kernel.org>]

From: Sean Wang <sean.wang@mediatek.com>

Introduce a dedicated NAN connection type for connac-based firmware.

This prepares driver support for NAN interfaces by allowing MCU
device/BSS configuration to represent NAN roles using a distinct
connection type.

No functional behaviour change yet as NAN is not exposed to userspace.
