qcacld-3.0: Add support to set primary STA interface

Add support to primary STA iface when there are more
than one STA iface concurrently active via the
SET_WIFI_CONFIGURATION vendor command.

Below attribute associated with this vendor command to
give indication to host to set primary interface:
QCA_WLAN_VENDOR_ATTR_CONFIG_CONCURRENT_STA_PRIMARY.
Set indicates that the specified iface is the primary
STA iface.

This configuration helps the firmware/chip to support
certain features (e.g., roaming) on this primary interface,
if the same cannot be supported on concurrent STA ifaces
simultaneously.
This configuration is only applicable for the STA iface and
gives the priority for it only over other concurrent STA
ifaces. 1-Enable, 0-Disable.
