[qca-nss-clients] Add MSCS client module

This patch adds a new NSS client module for Mirrored Stream
Classification Signalling(MSCS) feature. ThisMSCS clients module acts
as interface between WLAN host driver and ECM Classifier module.
WLAN host driver provided callback to this client for wifi peer look up
based on src mac address.MSCS client registers same callback from wlan
driver to ECM MSCS classifier which is invoked during flow acceleration to
get valid QoS Tag.
