wifi: mt76: mt7996: select net_setup_tc handler at runtime

Browse Source 
The net_setup_tc callback is chosen at compile time and the WED
handler shadows the NPU one when CONFIG_NET_MEDIATEK_SOC_WED is
enabled. mt76_wed_net_setup_tc() returns -EOPNOTSUPP without an
active WED device, so on boards using the Airoha NPU with a WED
enabled kernel the tc offload block is never bound and PPE flow
offload for wireless traffic is silently disabled.

Dispatch on the active offload backend instead: use the WED handler
when a WED device is attached and fall back to the NPU handler
otherwise. Builds without MT76_NPU keep the old behavior through the
mt76_npu_net_setup_tc() stub.
