Add QCA vendor command/event and attributes for peer rate statistics

Peer rate statistics is per-peer cached data in the driver. These
statistics needs to be flushed to a user space application on
synchronous/asynchronous events. This command is used as an event from
the driver to flush per-peer cached statistics to the application.
