qcacmn: Handle vendor control command and event

WMI_ROAM_GET_VENDOR_CONTROL_PARAM_CMDID: Add support
for a new roam command to get vendor control parameters
from FW. Host needs to send proper param ID in command
(from enum WMI_ROAM_GET_VENDOR_CONTROL_PARAM_ID)
to get corresponding INI value from FW.

WMI_ROAM_GET_VENDOR_CONTROL_PARAM_EVENTID:
Add support for a new roam event to get param value
from FW. FW sends this event upon receiving
WMI_ROAM_GET_VENDOR_CONTROL_PARAM_CMDID command.

Change-Id: Ic7b3badb14daff183dd36927b4dae6bbc036e6cd
CRs-Fixed: 3225166
