We can't have two copies of |embedder.dart| or |shell.dart| because they take
ownership of some underlying Mojo handles. Instead of duplicating the code,
this CL makes the old locations just export all the symbols from the new
location. I've also done the same with fetch.dart to avoid code duplication.
Finally, I've removed image_cache.dart in the old location because the only
clients already live in the new world and ought to use the new location.

Some files are moved by this:
Copy framework/node.dart into types/ - preparing for framework/'s decomissioning.
Move app/scheduler.dart into sky/scheduler.dart - "app" doesn't really make sense.
As part of the SkyBinding cleanup, I made the hit-testing less
RenderBox-specific, by having the HitTestEntry.target member be a
HitTestTarget, which is an interface with the handleEvent() function,
which is then implemented by RenderBox. In theory, someone could now
extend hit testing from the RenderBox world into their own tree of
nodes, and take part in all the same dispatch logic automatically.
This involved moving all the hit testing type definitions into a new
sky/hittest.dart file.
Renamed SkyBinding._app to SkyBinding._instance for clarity.
Moved code around in SkyBinding so that related things are together.
Made WidgetSkyBinding use the existing SkyBinding.instance singleton
logic rather than having its own copy.
I also added some stub README.md files that describe dependencies.

NOTE: This CL appears far larger than it actually is for two reasons:
1) Many files were moved around to use the Dart package directory structure.
2) Many .dart files had to have import paths updated.
- Organize mojo/public/dart so that it uses standard Dart package layout
- Organize mojo/dart/apptest so that it uses a standard Dart package layout
- Organize sky/sdk so that it uses a standard Dart package layout
- Create a mojo/testing package (used by unittests)
- Introduce the 'dart_pkg' gn rule which populates gen/Config/dart-pkg
- All internally vended Dart packages must have a corresponding dart_pkg rule
- It is now possible to use dependency_overrides: in pubspec.yaml to mix internal and external package dependencies (enables analyzer, editor, webstorm usage for internal developers).
- Package root for dart content handler ends with "packages/"
- Imports of mojo package uris no longer need the "public/dart"
- mojo/public/tools/dart_package.py is a clone of mojo/public/tools/gn/zip.py
- Sky tests no longer run 'deploy_sdk' script.
