Detect Flutter SDK location relative to Dart SDK (#3045)

* Detect Flutter SDK location relative to Dart SDK

If the Dart SDK is present inside the Flutter SDK in sub-folder
`bin/cache/dart-sdk/`, then we no-longer require the environment
variable `FLUTTER_ROOT` to be specified. Instead we simply derive
the location of the Flutter SDK from the location of the Dart SDK.

We still allow the environment variable `FLUTTER_ROOT` to override
the otherwise automatically detected Flutter SDK location.

* Check that "version" file is present before deciding that we have found a Flutter SDK
