boot: Remove legacy extension board support

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.
