Matt Perry 10ca050890 Replace C++ UpdateTask with an empty dart version, loaded as a snapshot.
This adds a new placeholder dart package updater in sky/packages. This is built
into a snapshot and compiled into the Sky engine binary using the same
mechanism as the Dart isolate.

I also added a SkyHeadless class, similar to SkyView, used for running Dart
code without a view.
