RDKB-63482: wifi: MLO reconfiguration improvments and DML updates

[WellPeter]

Reason for change:

• Remove mld_apply parameter from codebase (no longer needed)
• Remove mld_addr from DB schema; compute it at runtime from BSSID
• Make old MLO DML parameters read-only
• Add Device.WiFi.SSID.{i}.X_RDK_MLDLinkID DML parameter
• Unify MLO group validation into shared mlo_update_all_groups() used by both webconfig and DB init paths
• Add is_mlo_config_matching() to enforce SSID, password and security mode consistency before forming an MLO group; WPA3 variants treated as inter-compatible across bands Test Procedure:
  • Verify MLO groups can be configured via DML: Device.WiFi.SSID.{i}.MLDUnit Device.WiFi.SSID.{i}.X_RDK_MLDLinkID
  • Verify MLO groups are correctly formed on DB init and webconfig
  • Verify MLO groups are correctly updated when changing SSID, password or security mode of an existing MLO group member Risks: Medium
    Priority: P1

Depends on rdkcentral/rdkb-halif-wifi#103

Pull request overview

This PR updates the OneWifi MLO (802.11be) configuration flow by removing deprecated MLO fields from webconfig/DB, adding a new SSID-level DML parameter for link ID, and centralizing MLO group validation/propagation so both DB-init and webconfig paths form consistent MLO groups.

Changes:

• Removed mld_apply handling across webconfig encode/decode/validation, config-change detection, DML, and OVSDB schema/gen.
• Removed mld_addr from the OVSDB schema (compute/propagate runtime MLD MAC from BSSID/main link) and added boot-time MLO group initialization after BSSID population.
• Added Device.WiFi.SSID.{i}.X_RDK_MLDLinkID and introduced shared update_mld_groups() + is_mlo_config_matching() (SSID/key/security consistency, with WPA3 variants treated as compatible).
