qcacld-3.0: Support obtaining thermal level for non-offload case

Currently thermal level can be got from upper layer only
for FW thermal mgmt offload case. Per the requirement,
refine the code to support it for thermal non-offload
case as well.
Similar to offload thermal mitigation, add TX_OFF and
shutdown two states for non-offload case. Host will fully
stop TX traffic in TX_OFF state and target will trigger
shutdown when temperature come to the range of shutdown.
Per above requirement, add below four INI to configure
thermal temperature threshold value as need for TX off
and target shutdown.
