Before this CL the test fails because we land on the "await" when
stepping out of "helper" as "helper" is executed synchronously (i.e.
the call to await (which is translated into a call to an await-helper)
hasn't executed yet so landing on it is "correct").
This CL changes the test so "helper" is not executed synchronously by
adding an "await null;" as the first thing in the test. Once we step out
we thus have already executed the "await" and doesn't land on it.
An alternative fix would have been to pass --no-sync-async.

The VM debugger expects _completeOnAsyncReturn to be called when
returning from an async function for stepping out of the async function
to work.
This CL does just that.
Note that `_completeOnAsyncReturn` only exists in the VM, but as
the async transformation is only run for the VM target that shouldn't
be a problem.

Previously, if we didn't include the source code, we wrote the url as
null. This for instance made it impossible to step through mixed in code
(at least when mixed in from the sdk).
This CL includes all used urls. If there's no source, the source is empty,
but the VM then tries to find the proper source to be able to display it
(e.g. the VM already has the sdk source).
This CL further more adds a service test that tests that we can actually
step into mixin in code from the sdk.

Prior to this change we only had fileOffset which points to the name.
This CL adds a field - startFileOffset - that points to the start
(e.g. 'static', 'factory', the return type or any presiding annotation
(including '@')), as well as fixing `Function::GetSource` in the VM to
fix a crash when using mirrors to ask for the source of a function or
constructor.
The field is added to procedures, constructors and classes.
The latter changes the location of classes with annotations to be
the position of the annotation. This is on-par with --no-preview-dart-2.
The change in regards to procedures and constructors mean, that both
the location and the source (from .location and .source on a
MethodMirror) will change to include any annotations. This is a
different behavior than --no-preview-dart-2.
Closes#33271.

In most cases the correct fix is to simply drop the generic comment
syntax (e.g. replace "List/*<Map>*/" with "List"). We can't use the
more precise type because the runtime type is actually more general
(e.g. when processing an object that came from the JSON parser, all
lists have runtime type List<dynamic>, even if their elements happen
to be uniform). But we can introduce more precise types when handling
substructures.
Exception: all JSON-derived maps have type Map<String, dynamic> (since
JSON maps always have string keys), so we can use a more precise type
when dealing with JSON maps.

If there is registered expression compiler, VM debugger uses it to compile expressions. Otherwise, it will fallback to use kernel service compiler.
This is needed to support Flutter use case where compiler is running on developer's host machine, not on the device where VM is running.

Fixes#33170: We had an assert that type variables are not bounded by "dynamic".
This assert was previously valid because the FE replaces "extends dynamic" with
"extends Object". However, it's not necessary in any way, and it's difficult to
access the Object type from outside the FE when synthesizing type parameters for
expression compilation.
Fixes#33171: The synthetic class generated during serialization to hold the
synthetic method may need to extend core library classes if the expression's
scope was within a core library class. In this case, the class finalizer needs
to avoid applying the restrictions on class extension to the synthetic class.
To facilitate this, we now use a single class name for all synthetic classes,
rather than copying the original class name. The name of the synthetic class has
no function at all, since the synthetic method is reparented to the original
class before execution.
Fixes#33239: The arguments descriptor passed to InvokeFunction for expression
functions which capture generic type parameters was using the wrong argument
count.
Fixes#33270: Use LookupClassAllowPrivate instead of LookupClass when resolving
the expression's scope in the VM.

For brevity we explicitly downcast the parameter type (using "as")
rather than implicitly downcasting it (by assigning to a fresh
variable). Since this is test code, I'm not concerned about the
performance penalty of the explicit downcast.

In some cases we need to specify a type because the inferred type
would be too specific. For example, in the code:
final content = [new SampleBufferControlElement(...)];
...
content.addAll([new BRElement(), ...]);
Strong mode would infer a type of `List<SampleBufferControlElement>`
for `content`, making it impossible to add other kinds of HTML
elements to the list later. So we have to specify explicitly that the
list element type is meant to be `HTMLElement`.
In other cases we need to specify a type because the inferred type is
too general. For example, in the code:
Future<List<String>> complete(...) {
var result = [];
...add values of type String to `result`...
return new Future.value(result);
}
Strong mode would infer a type of `List<dynamic>` for `result`, making
it impossible to enclose in a `Future<List<String>>`. So we have to
specify explicitly that the list element type is meant to be `String`.

This CL makes the following changes, which should be safe since they
don't affect Dart 1.0 semantics:
- Explicitly declare the types of certain variables as `dynamic` to
avoid strong mode inferring a type that leads to errors.
- Explicitly cast certain expressions to `dynamic` to allow access to
members that are dynamically known to be present.
- Add `covariant` annotation to method parameters that are a subtype
of the corresponding parameter in the base class.

With this change debugger requests yield(await) positions from kernel builder so it can confirm which frame handles what exceptions.
This also renames ':completer' to ':async_completer' in constructed kernel, so it is compliant with what VM expects to see(and updates test expectations accordingly).
Further it fixes async stack navigation for sync-async that became default in dart vm since first version went for the review((uses `future` getter, rather than property).
It also makes `future` getter non-debuggable to allow stepping-out of async methods.
Make Handle zone-scoped. Clean up frame counter var name.
