qcacmn: Add support to extract the channel info from RTT measreq

Add support to extract the freq, cfreq1, cfreq2, PHY mode, Destination
macaddr, and channel BW values from the RTT measurement request buffer
received from the LOWI application. Pass these values to a registered
callback. Users can use these values to make some decisions on the RTT
scan.
