Before, OneChildListRenderNodeWrappers were responsible for removing
the child nodes' RenderCSS nodes from their containers, and for moving
those around when nodes were reordered. Now, they're also responsible
for adding them.

Rect is now a dart-only type, defined in its own .dart file. I use
DartConverter when passing a Rect into C++. I also special-cased Rect in the
IDL compiler so that it's passed by value, instead of allocating a new
Rect object on the heap.

This also adds a mechanism to add custom .dart files to dart_sky.dart - used by
Rect.dart.

Clients can now register a callback that gets called whenever we have an event
for the view. We'll need to update the Event class at some point, but this is a
start.

Several people have run into trouble building Sky because of a missing
dependency in the build. From inspection, it looks like this might fix the
issue, but it's hard to be sure without being able to reproduce the issue
locally.

Per discussion about https://codereview.chromium.org/1093633002 it
appears that we don't have a way around having a parent pointer after
all, so this exposes it.

It also renames setAsChild() to adoptChild() for better readability.

The SkyView interface will replace WebView as the interface to the SkyEngine.
The SkyView interface won't have a root level Document or Frame object but
instead will implement the base layers of the framework.

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.

The style syncing logic that was in OneChildListRenderNodeWrapper is now in RenderNodeWrapper.
TextFragment and Image now just inherit directly from RenderNodeWrapper.
OneChildListRenderNodeWrapper now only deals with syncing children.

This lays the groundwork for supporting RenderNode classes that have more complicated child setups.

This creates a new RenderNode class that does positioning.
It then creates an fn Container class that uses it just to position things at 0,0 at the full extent of the container.

Previously, the fn "Text" class rendered as a single block of text.
Now, there's a "Paragraph" class that contains "TextFragment"s, and "Text" is just a component that places a single TextFragment into a single Paragraph.
This allows other components, notably the Input component, to build more complicated paragraphs of styled text, without using 'display'.
