From: Harshitha Prem <quic_hprem@quicinc.com>

Add support to process WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT
service bit. If this service bit is set by firmware, then it expects
host to set rx_peer_meta_data_ver in wmi_resource_config's flags2
with value 3 for QCN9274 to indicate as V1B meta version. If this is
not set firmware crash is seen during peer addition.

Hence, if WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT service bit
is set by firmware, set correct peer metadata version to avoid
firmware crash.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00188-QCAHKSWPL_SILICONZ-1
