Basic view management for engine classes (#42991)

_This PR is part of the multiview engine project. For a complete roadmap, see [this doc](https://docs.google.com/document/d/10APhzRDR7XqjWdbYWpFfKur7DPiz_HvSKNcLvcyA9vg/edit?resourcekey=0-DfGcg4-XWRMMZF__C1nmcA)._

------

This PR adds view management to all engine classes that need it. View management here basically means `AddView` and `RemoveView` methods, and most importantly, how to handle the implicit view.

The implicit view is a special view that's handled differently than all the other "regular views", since it keeps the behavior of the current single view of Flutter. Detailed introduction can be found in `Settings.implicit_view_enabled`.

The following two graphs show the difference between initializing with/without the implicit view and creating regular views.

Flutter Engine

OpenSSF Scorecard SLSA 1

Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.

If you want to run/contribute to Flutter Web engine, more tooling can be found at felt. This is a tool written to make web engine development experience easy.

If you are new to Flutter, then you will find more general information on the Flutter project, including tutorials and samples, on our Web site at Flutter.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.

Flutter is a fully open source project, and we welcome contributions. Information on how to get started can be found at our contributor guide.
