Includes the following changes:
- Disable type checking in the service isolate when strong mode is
turned on. We don't yet have strong mode clean vmservice Kernel
binary available (Issue #31203);
- Introduce new Dart VM API to allow creating List<T> (T in {String, int}).
Current API only allows to create List<dynamic> and in strong mode
List<dynamic> is not assignable to List<T>. For now we limit this API to
a fixed number of core types for performance considerations (type
arguments can be canonicalized and cache ahead of time). We will
extend the API allowing creation of arbitrary List<T> if we will
discover the need for it later;
- Use this new API to fix CreateRuntimeOptions to create List<String>
and not List<dynamic>;
- Likewise fix OneByteString_splitWithCharCode to return List<String>
and not List<dynamic>;
Additionally this CL refactors how getters and setters are created
in object_store.h removing 500 lines of largely boilerplate code.

To run a script with the Dart->Kernel parser, use the -dfe option:
dart --dfe=runtime/tools/kernel-service.dart --packages=/src/d2/sdk/.packages foo.dart
The front end expects a directory named patched_sdk in the build directory (patched_sdk should be a sibling of the directory that contains the dart executable.)
Warning: using a debug build dart executable is very slow. It takes 2 minutes to run Hello World in a debug build, and about 7 seconds in a release build.

Process::Exit does not do the normal shutdown procedure - this CL avoids
a crash in the static destructor of the loader info lock by making it
new-allocated.
Also remove --shutdown flag since the clean shutdown procedure is on by
default since a while now.

This cl implements an experimental filesystem maintained in the vm, called dart-devfs. This will allow service protocol users to read and write source files while the vm is running. This is needed for the reload support for flutter.

Release and debug precompilation VMs start the service isolate, but do
not wait for it to startup (it is there to support Observatory and not
for loading). The main isolate can finish and the VM begin to shutdown
before the service isolate runs main. Handle this case.

This change add the ability to restart the vm through the service
protocol. All isolates are killed, and then the main isolate is
restarted cooperatively by the embedder.
This change also fixes the message handler to prevent it from
accidentally ignoring vm shutdown messages.
Previously, we would stop handling messages whenever we hit an error
(such as a compile error or an unhandled exception). This would leave
shutdown requests sitting the oob queue, neglected.
We now process *all* oob requests, up to the first shutdown request.
When we hit a shutdown request, we clear the oob queue and process no
more messages.
To make all of this work, we had to change the return value of
HandleMessage from bool to a new enum type, allowing the message
handler to distinguish *normal* error cases from the more rarified
shutdown and restart cases.

A CL from July (https://codereview.chromium.org/1168933002), papered over (see ASSERT removal in dbg_message.cc) a bug where we would send isolate shutdown event for the service isolate even though no isolate create event was sent.
This CL:
- Restores the ASSERT in dbg_message.cc
- Fixes the service isolate shutdown path so that the shutdown event is no longer sent.
