Extracts `updatePathClipViewsWithPaths:origin:` which updates the stack of AppKit clip views hosting the platform view. This change is a cleanup change for readability and makes no semantic changes to how mutator views are applied. Existing unit tests in [FlutterMutatorViewTest.mm](https://github.com/flutter/engine/blob/main/shell/platform/darwin/macos/framework/Source/FlutterMutatorViewTest.mm) are expected to pass without changes. This is refactoring prior to applying a fix for rotation handling.
