wifi: ath12k: Advertise encapsulation/decapsulation offload support to mac80211

Browse source 
Currently, the mac80211 layer handles construction and parsing
of 802.11 headers during packet transmission and reception.
Offloading encapsulation and decapsulation to hardware can
significantly enhance performance. Check the service bit to determine
if the firmware supports Ethernet offload. If supported, advertise the
capability to mac80211 to bypass software-based 802.11 header
processing.
