We want to be able to emit variance information in DDC and this flag was gating the variance checking logic in `rti.dart`.
Set to `true` by default since we can't use the feature without the experiment enabled anyways.

Update source code in tests to be migrated to null safety. Tests are
still running in unsound null safety.
In most cases types are now inferred to be non-nullable so the code that
makes expressions to be seen as nullable now require `as dynamic` to
allow them to compile.
Update nullable inference logic to recognize `.toString()` on a String
as non-nullable in code that has been migrated to null safety.

This adds support using experimental features in id testing in DDC and
uses it to add tests for scopes in extensions, extension types and
mixins.
The tests show that the DartScopeBuilder and DartScopeBuilder2 differ
on the scope on instance members in extensions and extension types for
the synthetic #this variable.

Some SDK only inline helper methods expect specific types passed to
them. These expectations can't be enforced by the type system and
everything is currently working properly. Extension methods may cause
confusion in the future so this change adds a bit more context to
the error messages just in case.

The @dart marker should only be used for released language versions,
rather than the upcoming release, since the upcoming language features
has not been finally assigned to a language version yet. The appropriate
experiments should be used instead to opt into upcoming features.
This change is part of the effort to make it possible to easily bump
tools/VERSION without unexpected issues whenever tests have to have
their pinned language versions updated as well.

- Add a new dart2js preamble file that seals the native object prototype.
- Use the file when running DDC in d8 locally.
Once this change lands the new preamble can be used in the script that
runs d8 on the benchmarking bots.
If benchmark results look good, I will followup with a change to enable
the prototype sealing in SDK test configurations as well.

DartType.extensionTypeErasure can be used by backends to easily

Adds simple method inlining for select patterns only in the dart:_rti
library as an optimization. This helps avoid chains of costly
accesses method calls that in the end simply perform a single
operation and return the result.
For example and snipet from the compiled SDK before:
```
if (_rti._isString(object)) {...}
```
and after:
```
if(typeof object == "string") {...}
```

This CL introduces StructuralParameter and StructuralParameterType
classes. They are intended to replace TypeParameter and
TypeParameterType respectively where those were used as type
parameters defined by FunctionTypes. Previously, type parameters of
FunctionTypes were represented by TypeParameter objects with the
‘parent’ field set to null. By introducing StructuralParameter and
StructuralParameterType this CL unambiguously separates the two
notions of type parameters.
