Add mt76_connac_spe_idx() for antenna mask to spatial extension
index conversion. This is used to support flexible control of
tx antenna.

Ryder LeeandFelix Fietkau 873365b06c wifi: mt76: add PPDU based TxS support for WED device
Given that there's no data coming from network stack for binding flows,
hence driver counts and reports station's statistics directly through
NL80211_STA_INFO_* based on active PPDU based TxS for offloading data.

Apart from that, WA firmware and its offloading engine (SDO) have hardcoded
"2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting.

Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST.

Felix Fietkau af406a2d1c mt76: do not use skb_set_queue_mapping for internal purposes
Previously the code used skb_set_queue_mapping for management or non-bufferable
powersave frames that need to be sent to a different hardware queue.
This can confuse AQL, which expects the value to remain the same until the tx
status report.
The only place that currently uses the altered skb queue mapping is the txwi
write function. Change the code to pass the hardware queue id as a function
parameter instead.
