octeontx2-af: npc: cn20k: Clear MCAM entries by index and key width

Replace the old four-argument CN20K MCAM clear with a per-bank static
helper and npc_cn20k_clear_mcam_entry() that takes a logical MCAM index,
resolves the key width via npc_mcam_idx_2_key_type(), and clears either one
bank (X2) or every bank (X4).

Call it from npc_clear_mcam_entry() on cn20k and log when key-type lookup
fails. Use the per-bank helper from npc_cn20k_config_mcam_entry() for
pre-program clears.

For loopback VFs, use the promisc MCAM index as ucast_idx when copying RSS
action for promisc, matching cn20k default-rule layout.
