Chris Bracken 49afcc0101 [macOS] Refactor PlatformView mutators (flutter/engine#42130) ...

This refactors `[FlutterMutatorView applyLayer:]` to split out orthogonal behaviour into smaller functions for better readability/maintainability.

Extracts:
* General transform composition to CATransformFromMutations
* Opacity handling
* MasterClip computation
* RoundedRectClip computation

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.
