147	* Has Own Method
148	*
149	* Used for check whether the method passed as a parameter was declared in the current instance or inherited.
150	* If a base_class_name is passed, it checks whether the method was declared in that class. If the method's
151	* declaring class is the class passed as $base_class_name, it returns false. Otherwise (method was NOT declared
152	* in $base_class_name), it returns true.
153	*
154	* Example #1 - only $method_name is passed:
155	* The initial declaration of `register_controls()` happens in the `Controls_Stack` class. However, all
156	* widgets which have their own controls declare this function as well, overriding the original
157	* declaration. If `has_own_method()` would be called by a Widget's class which implements `register_controls()`,
158	* with 'register_controls' passed as the first parameter - `has_own_method()` will return true. If the Widget
159	* does not declare `register_controls()`, `has_own_method()` will return false.
160	*
161	* Example #2 - both $method_name and $base_class_name are passed
162	* In this example, the widget class inherits from a base class `Widget_Base`, and the base implements
163	* `register_controls()` to add certain controls to all widgets inheriting from it. `has_own_method()` is called by
164	* the widget, with the string 'register_controls' passed as the first parameter, and 'Elementor\Widget_Base' (its full name
165	* including the namespace) passed as the second parameter. If the widget class implements `register_controls()`,
166	* `has_own_method` will return true. If the widget class DOESN'T implement `register_controls()`, it will return
167	* false (because `Widget_Base` is the declaring class for `register_controls()`, and not the class that called
168	* `has_own_method()`).
169	*
170	* @since 3.1.0
171	*
172	* @param string $method_name
173	* @param string $base_class_name
