Move the extension_overlay_cmd execution out of the core extension framework to the command level. This decouples the framework from command-specific behavior and prepares for future extension support in other boot flows.

boot: Remove legacy extension board support 2025-11-03T16:02:39+00:00 Kory Maincent (TI.com) kory.maincent@bootlin.com 2025-10-30T16:45:09+00:00 2d12958ee71b5f400ff2045aebc9730e8e219340 Remove the legacy extension board implementation now that all boards have been converted to use the new UCLASS-based framework. This eliminates lines of legacy code while preserving functionality through the modern driver model approach. Update the bootstd tests, due to the removal of extension hunter.
