[PATCH ath-next 3/3] wifi: ath12k: Advertise encapsulation/decapsulation offload support to mac80211

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. This can be achieved by
having the driver advertise hardware support to mac80211 to
bypass 802.11 header processing

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00217-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
