wifi: ath12k: add dp_mon support 32-bit TLV headers

Browse source

Wi-Fi 7 monitor status parsing in dp_mon currently assumes a 64-bit TLV
header and directly decodes tag/len/userid from struct hal_tlv_64_hdr.
On chips using a 32-bit TLV header (e.g. QCC2072), this causes monitor RX
status packets to be dropped during TLV parsing.

Introduce HAL helpers to decode TLV header fields (tag/len/userid/value)
for both 32-bit and 64-bit header layouts. Without changing the actual TLV
parsing logic.

Tested-on: QCC2072 hw1.0 PCI WLAN.COL.1.0.c2-00068-QCACOLSWPL_V1_TO_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3
