Previously, a valid web socket connection would use the following URI:
`ws://127.0.0.1/ws`
Now, by default, the VM service requires a connection to be made with a
URI similar to the following:
`ws://127.0.0.1:8181/Ug_U0QVsqFs=/ws`
where `Ug_U0QVsqFs` is an authentication code generated and shared by the
service.
This behavior can be disabled with the `--disable-service-auth-codes`
flag.

- Not removing the flag from flag_list for now as it is used in a number of tests and removing it from all these places would be a big change, it would be a NOP flag
- removed some dead code in 'loader.dart' which was invoked from the tag handler

The `@pragma` annotation on `vmservice_io.main` is modified to only mark it as a
root on non-product builds. Since the annotation is evaluated in the constant
transformation, we need to thread a flag through `gen_kernel.dart` indicating
whether the Kernel produced should target a product precompiler.
# Test Plan
Tested locally on Flutter. Unfortunately it's not possible to test the scenario where
`vmservice_io` is not included, since we don't have any "product" bots. Soon the
flag will be introduced into Flutter, and we will have some coverage from there.

In 5a44162c97 in attempt to adhere to declared
method signatures we lost zero-copying JSON decoding of responses from
VM: `Message.sendToVM` was changed to always decode the response into
string before passing it to the caller and the logic to use fused
JSON decoding was removed. This increased peak memory consumption by
the VM Service.
This commit addresses the issue by restoring the zero-copying JSON decoding
logic while adding a wrapper around responses that make it clear what kind
of data is passed around and how that data is encoded and handled.
We introduce a class `Response` which can contain either a Dart string, a
binary data (represented as a Uint8List) or utf8 encoded string (represented
as a Uint8List). This class is used in all places where previously a String
or dynamic were used, e.g. MessageRouter.routeRequest is changed to return
Future<Response> rather than Future<String>. This allows callees to
decode JSON responses without copying them into Dart heap while
maintaining sufficient level of typing to make the code easy to reason about.
This commit also removes some dead code from the VM service related to old
Service API and TAR assets unpacking (which has been long done in C++).

A new RPC is introduced `_registerService` which allow clients to
register new services that are accessible from all the other clients.
Each registered endpoint is identified by 3 strings:
- `service`
a non empty string which identifies the provided service
(e.g. `HotReload`, `OpenFile`)
- `alias`
an alias for that particular endpoint used by clients to identify it
(e.g. `Flutter`, `IntelliJ`)
- `method` __generated__
the RPC method that should be invoked from a client to request it
A new _stream_ `_Service` is introduce, and two related events:
- `ServiceRegistered`
which is triggered when a new client is registered.
All the related information (`service`, `alias`, `method`) are sent.
- `ServiceUnregistered`
which is triggered when a client, which previously registered a
service, disconnects.
Just `service` and `method` are sent.
