Add QCA vendor subcommand to suspend/resume AP interface

Add a new QCA vendor subcommand QCA_NL80211_VENDOR_SUBCMD_AP_SUSPEND to
allow suspend and resume the AP interface. When an AP is suspended, it
disconnects all connected clients and stops all TX/RX operations on the
AP interface. The driver retains the AP configuration and on resume, all
AP operations are resumed with the same configuration.

This subcommand is also used in the event path to notify userspace about
AP suspended or resumed state changes.

This uses attributes defined in enum qca_wlan_vendor_attr_ap_suspend.
