qcacld-3.0: Add support to compile connection manager STA+STA roam API

Enable compilation of the connection manager roam files with
Kbuild changes.
Add new API to store and retrieve the firmware scan channels at
mlme. Also add initial support to post SET_PCL command through
lim, so that it is not sent before ROAM init command.

Add changes to restrict connection of the 2nd STA to
channels on the other band of the 1st STA connected band.
This is done by filling only the allowed band channels in
the scan filters for the 2nd STA connection. If only
1 STA is active, it is allowed to connect on any band.

Add header gaurds for missed header files:
wlan_cm_tgt_if_tx_api.h
target_if_cm_roam_offload.h
