Implement framework interface for the dialog window archetype (#176202)
## What's new?
- 🍏 Added the concept of dialogs to the windowing API. New
symbols:
   - `DialogWindowControllerDelegate`
   - `DialogWindowController`
   - `WindowingOwner.createDialogWindowController`
   - `DialogWindow`
   - `WindowControllerCommon`
- 🥘 Introduced the `WindowControllerCommon` mixin to
share common windowing functionality between controller types
- I have NOT yet implemented dialogs. This pull request ONLY adds the
idea to the API. Win32 implementation to follow :)

Notes

Note on Gradle wrapper files in .gitignore:

Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
