@Experimental is already defined in dart:html. Adding the same
annotation to dart:core breaks the build. Removing the annotation from
dart:html and adding it to dart:core is a breaking change, e.g.
if someone has said "import 'dart:html' show Experimental".
This annotation is for use in the upcoming dart:standalone with
the waitFor(Future f) function:

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++).

These members were defined as returning Future<Socket>, but the

reason these members need to return Future<Socket> anyway, so just
change them to return Future<dynamic>.

The only fix needed for relanding is adding _ensureScheduleImmediate
to the list of vm entrypoints in //runtime/vm/compiler/aot/precompiler.cc
Original commit message:
Adds a top-level call waitForEventSync to dart:io that blocks the
thread an Isolate is running on until messages are available.
Before the thread blocks, the microtask queue is drained.
Before waitForEventSync returns, all messages are handled.
Lifting this up from a comment:
This is apropos of the request that nweiz@ sent to the mailing list a
couple weeks back. I'm not sure we should land this. We certainly
shouldn't land it without some annotations that will make the analyzer
complain a lot in most configurations, but I don't know what those

There were two situations where this could get into a bad state:
* If the sink already had an error, _isBound would be set to true and
never unset. This is fixed by not setting it at all if an error
already exists.
* If _controllerCompleter completed to an error, _isBound would never
get set back to false. This is fixed by refactoring the code so that
the appropriate whenComplete() is always run.

Without strong mode, a "good enough" implementation is to simply call
the generic method with "dynamic" for the type arguments, which is what
this does. That should be enough to unblock our internal users.
We also need to not report a compile error when
dart_internal/extract_type_arguments.dart imports the hidden
"dart:_internal" library.
This patch does both of those for the VM and dart2js (using its old
front end).
Note that the test still fails because the test is more particular than
most actual user code would be -- it validates that the instantiated
type arguments are *exactly* correct, and not that the returned object
is merely subtype compatible.

VMService.routeRequest of type Future Function(Message) overrides
MessageRouter.routeRequest of type Future<String> Function(Message).
It not enough to just fix VMService.routeRequest's return type because
Message.sendToVM() violates its type signature: it declares to
return Future<String> but in reality it returns Future<dynamic>
which can complete with either String or List. This CL addresses
this issue as well.

The informal spec for strong mode top level inference
(https://github.com/dart-lang/sdk/pull/28218) says "If there are
multiple overridden/implemented methods, and any two of them have
non-equal types (declared or inferred) for a parameter position which
is being inferred for the overriding method, it is an error."
This CL fixes several SDK errors that arise from this rule. For
example, the classes _Closure, Function, and Object contained members
declared as follows:
class _Closure implements Function {
bool operator ==(other) ...
}
class Function {
bool operator ==(Object other) ...
}
class Object {
bool operator ==(other) ...
}
The type of Object's operator == was (dynamic) -> bool; the type of
Function's operator == was (Object) -> bool; therefore the type of
_Closure's operator == (which overrides both, since _Closure extends
Object and implements Function) cannot be inferred and must be
specified.
A similar situation exists for _Double and _IntegerImplementation
(both implement num, which declares operator == to have type (Object)
-> bool), and _Uri (which implements Uri, which declares operator ==
to have type (Object) -> bool).
This CL fixes the error by specifying the type explicitly in the
classes _Closure, _Double, _IntegerImplementation, and _Uri.

There is no actual implementation here yet (that's your job :) ), but there is:
- An external method in dart:_internal, extractTypeArguments().
- Empty patch methods for that for the VM, dart2js, and DDC. These need to have implementations
filled in.
- A "dart_internal" package to expose a subset of the API. It gives you:
extractListTypeArgument()
extractMapTypeArguments()
We'll bring this into Google, but not publish it externally unless we find we really need to.
- A test for the behavior. It probably has bugs since I can't run it.
