Calling new on an Editor should suggest to use Editor.CreateEditor()

[citizenmatt]

Given a class that derives from Editor, if calling new MyEditor(), Rider will suggest to rewrite this as ScriptableObject.CreateInstance<MyEditor>(). However, since it's an Editor class, it should actually rewrite as Editor.CreateEditor($TARGET$).

• It might be better to suggest Editor.CreateEditor($TARGET$, typeof(MyEditor)), in case there are multiple editors for the given target type, and new was being called on a specific type.
• Look at the editor type and find the [CustomEditor(typeof(_target_))] to find the type of the target object, and filter suggestions for $TARGET$ based on this type.
• Possibly suggest Editor.CreateEditor or Editor.CreateEditorWithContext to allow passing in a context object. I don't know how to suggest what the context object should be.
