qca-wifi: Add RDK statistics cache module code
Define cache module code required for RDK-B statistics : a. Objects to maintain tx and rx rate related statistics b. Interface objects to be use by dp while pushing stats to module c. Northbound interaction specific IOCTL structures/enums d. WDI handlers for southbound interaction from dp to stats module. CRs-Fixed: 2407888 Change-Id: I50b1461bc415e957d224bb1ec56e5e94cd833c27
