wifi: cfg80211/mac80211: Add NL80211_IFTYPE_PD for PD PASN and PMSR operations

Browse Source 
Add a new wdev-only interface type NL80211_IFTYPE_PD to support
Proximity Detection (PD) operations such as PASN and peer measurement
operations. This interface type operates without a netdev, similar to
P2P_DEVICE and NAN interfaces.

Implement support across cfg80211 and mac80211 layers with PD-specific
checks gated by the NL80211_EXT_FEATURE_SECURE_RTT feature flag,
management frame registration and transmission capabilities, and proper
channel context handling where PD interfaces are excluded from bandwidth
calculations. Update mac80211 to recognize the new interface type in the
relevant paths for this management-only interface.

PD discovery can be performed on any available interface, such as
NL80211_IFTYPE_STATION.

If PD/PMSR uses the MAC address of an existing interface type, such as
NL80211_IFTYPE_STATION, then pairing and measurement shall use that
same interface. If PD/PMSR uses a different MAC address, such as a
random MAC address, then pairing and measurement can be performed on a
new NL80211_IFTYPE_PD interface created with that random MAC address.
