wifi: mt76: mt7996: add support for ERP CTS & HT protection

Browse source 
This patch adds support for handling BSS_CHANGED_ERP_CTS_PROT and
BSS_CHANGED_HT.

With this change, when the Wi-Fi driver needs to adjust its behavior for
compatibility or performance, especially concerning older 11g/n devices,
by enabling or disabling CTS protection frames, often for hidden SSIDs or
to manage legacy clients.

It also introduces debugfs options to manually control protection mode,
allowing users to select betweenno protection, RTS/CTS, and CTS-to-self.
