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.
Test Plan:
#33170: python tools/test.py -m debug -c dartk --strong service/evaluate_function_type_parameters_test
#33171: python tools/test.py -m debug -c dartk --strong service/eval_test

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.

Leave some observatory tests to run in --no-sync-async modes as
changing these tests now would make them fail if somebody tries to run
them with the --no-sync-async flag. We can modify these tests once we do
not have a way to revert this flag.

This CL changes:
* package:kernel/clone.dart: To not clone file offsets if the
file-uri we copy from is unknown.
* package:kernel/binary/ast_to_binary.dart: To not write out file
offsets if the file-uri is not written/indexed (which happens if
the file uri is not in the `Program.uriToSource` map).
* It reverts the file renaming part of 60a2cfa219 which
fixed the name collision problem only partially (it missed to
rename `runtime/lib/double.dart`, which is not possible because
there's already a `double_patch.dart` file).
Instead of renaming, we solve the problem by mangling the names as follows:
.../sdk/lib/core/double.dart -> dart:core/double.dart
.../runtime/lib/double.dart -> dart:core/runtime/lib/double.dart
.../runtime/lib/double_patch.dart -> dart:core/runtime/lib/double_patch.dart
* It changes the test to ignore any negative token positions. The vm
service does not just expose `-1` token positions for places where
there is no source, but also e.g. `-9` (which means TokenPosition::kMethodExtractor),
this was one reason why the appjit test failed.
* It changes the test to try to force-compile everything (unsure if that works).

This makes sure we can distinguish e.g. 2 different timeline.dart files
(from runtime/lib/timeline.dart and sdk/lib/developer/timeline.dart)
This CL also fixes the owner of constructors to be patch classes, if
the constructors come from a patch.
This CL also adds a service/valid_source_locations_test, which loops
over libraries/classes/fields/functions and obtains source locations for
them, including line numbers. This ensures that if there is a source
location attached to a member, we can use it's token position to get to
the line number.
This CL also changes package:kernel's [Cloner] to clone fileOffsets (and
not just fileEndOffsets). This is important for mixin resolution, where
we copy members into mixin application classes.
