qcacld-3.0: Add support to get thermal throttle stats

Add support for sending WMI_REQUEST_THERMAL_STATS_CMDID
to request for the thermal stats via vendor cmd:
QCA_WLAN_VENDOR_ATTR_THERMAL_CMD_TYPE_GET_THERMAL_STATS
This vendor cmd can either be used to clear the thermal
stats or to request for the thermal stats.
Added ini gThermalStatsTempOffset, which can
configure thermal temperature offset value for capturing
thermal stats in  thermal range such as Thermal STATS
starts capturing from temperature threshold to temperature
threshold + offset.
If this ini is set to 0, then the events are disabled.
Also, add support for the FW event where the requested
thermal stats are sent in FW event
WMI_THERM_THROT_STATS_EVENTID().
The following attributes are sent in the events for every
level:
	STATS_MIN_TEMPERATURE
	STATS_MAX_TEMPERATURE
	STATS_DWELL_TIME
	STATS_TEMP_LEVEL_COUNTER
