qcacld-3.0: Vendor command support to enable/disable GTX

Add vendor command support to enable or disable GTX.
Currently there is no vendor attribute to enable/disable
GTX from vendor command. Add vendor attribute
QCA_WLAN_VENDOR_ATTR_CONFIG_GTX support through
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION vendor command
and with new wmi command WMI_VDEV_PARAM_GTX_ENABLE.
