Add QCA vendor interface to support Unsynchronized Service Discovery

Add a new QCA command QCA_NL80211_VENDOR_SUBCMD_USD and related
attributes to support Unsynchronized Service Discovery (USD).

Device in active subscriber role sends SDF frames with service
information to find devices that advertise or publish the required
services. Device address, operation type, instance id, service_id,
channel info, service specific info, element container attribute, and
timeout are sent to the driver to initiate USD publish or USD subscribe
operation. The driver sends QCA_NL80211_VENDOR_SUBCMD_USD event with
instance_id and the USD operation status. QCA_NL80211_VENDOR_SUBCMD_USD
is also used to update publish operation and to cancel the publish or
subscribe operation for a service. It also allows all the operations to
be terminated using the USD flush command.
