respect path_only option when an array is passed into url_for

The url_for method is now extracting the path_only option in order to determine if polymorphic_path or polymorphic_url should be called.

If the path_only option is not set it will be set to true unless the host option is set. This behaviour is the same as when a Hash or Params object is passed.

To support this unifying the code responsible for setting this default value has been extracted into a private method

actionview/CHANGELOG.md

+*   Respect the `only_path` option passed to `url_for` when the options are passed in as an array
+    
+    Fixes #33237.
+
+    *Joel Ambass*
+
 *   Deprecate calling private model methods from view helpers.
 
     For example, in methods like `options_from_collection_for_select`
