qcacld-3.0: Add pcl table for 4 SAP concurrency on MDM

To support 4 SAP concurrency on sdxlemur, they must work with mode
SAP+SAP(2g/SCC) & SAP+SAP(5g/SCC) or SAP+SAP(2g/SCC) & SAP+SAP(6g/SCC).

Add separate fourth_connection_pcl_dbs_table for mobile route devices,
adding 4 SAP cases, and modify policy manager to get pcl index when 4th
SAP being started.
