wifi: mt76: mt7915: add WDS support when WED is enabled

The current WED only supports 256 wcid, whereas mt7986 can support up to
512 entries, so firmware provides a rule to get sta_info by DA when wcid
is set to 0x3ff by txd. Also, WED provides a register to overwrite txd
wcid, that is, wcid[9:8] can be overwritten by 0x3 and wcid[7:0] is set
to 0xff by host driver.

However, firmware is unable to get sta_info from DA as DA != RA for
4addr cases, so firmware and wifi host driver both use wcid (256 - 271)
and (768 ~ 783) for sync up to get correct sta_info.

Currently WDS+WED config is completely broken on MT7986/7981 devices if
without this patch.
