qcacmn: Add support to process spectral scan detector info tlv

FW sends Spectral scan detector info TLV in WMI_PDEV_SSCAN_FW_PARAM
event to indicate the information of a detector participating in a sscan
session. FW sends one TLV of this type for each detector participating
in a spectral scan session. Add support to process the TLV and update
the spectral host data structures accordingly.
