-------------------------+-----------------------------
 This patch replaces spl_object_hash() usage with spl_object_id() in
 WP_Widget_Factory and _wp_filter_build_unique_id().

 Changes:
 - wp-includes/class-wp-widget-factory.php
 - wp-includes/plugin.php

 Reason:
 spl_object_id() returns an integer identifier internally assigned to an
 object, which avoids generating a hash string and is faster and more
 memory efficient compared to spl_object_hash().

 This improves performance in:
 - widget registration/unregistration
 - plugin filter callback identity generation


 Compatibility notes:
 - spl_object_id() requires PHP 7.2+
 - WordPress's minimum supported PHP version should be verified before
 merging this change.
 - Functionality remains identical since both are used only for object
 identity mapping.

 Testing:
 - Widgets register/unregister correctly
 - Filters/actions behave identically
 - No regression in callback uniqueness
