…r regular windows that always throws (flutter#172478)

## What's new?

- Added the `windowing` feature flag to the project
- Created the internal `_window.dart` API with support for regular
windows
- Implemented a `_WindowingOwnerUnsupported` implementation of the
`WindowingOwner` interface
- Marked all points of the public API as `@internal` with a
corresponding warning documentation
- Threw an `UnsupportedError` where it is appropriate to do so

Note that this PR does **NOT** include a real implementation of
`WindowingOwner` (e.g. for win32 or macOS). That work will be opened as
a follow up.

This work is based off of flutter#168697
and http://github.com/flutter/flutter/pull/168437, as well as this
design document:
https://docs.flutter.dev/go/multi-window-experimental-apis
