qcacmn: Add score based on EHT mode of operation

Previously, the Host driver assigned a minimum score of 1 to
any candidate, if the BSSID was in the deny list.

This commit introduces a change to prioritize candidates based on
their link type. The new scoring system adds more weight to MLO
over SLO and Legacy links. The priority order is as follows:
MLO 3-link > MLO 2-link > SLO > Legacy.
