Currently, dart:_js_types types are all typedefs in the web backends.
This leads to inconsistent semantics, since you can statically pass
Strings to JSString, for example. You cannot do this in dart2wasm.
In order to ensure consistent semantics, we reify these types using
a custom @staticInterop lowering. They all get erased to their
respective Dart type. When we have inline classes, these types
should be implemented using inline classes.
Note that Interceptor will not work for this use case. The reified
type of JS primitives are Dart types e.g. String, bool, and therefore
can not be casted to Interceptor.
In order to do this, the eraser is refactored and the JS backends use
shared erasure code to either erase/emit types.
Tests are added to make sure you need to go through a conversion or
cast to pass Dart objects to JS types.

Class used to be abstract, but lost it when made `final`.
There is no reason to allow instantiation, it's all static members.
Restablishing the `abstract` before we release 3.0, so we don't have to go through any extra steps.
The class is public, exported by `dart:io`. (Should probably also be documented.)

This CL replaces https://dart-review.googlesource.com/c/sdk/+/296900
The `List` constructor is removed in Dart 3.0.
Some of the `@patch` implementations were not removed.
This is *high priority*. It seems the left-over `@patch factory List` constructor did not cause any errors, instead it *added* a constructor to `List` that can be used in web compiled code. Even if `List` doesn't have such a constructor in the SDK code proper.
The VM and analyzer will say the invocation is an error, but dart2js happily compiles it and runs.
(It used to be that patches couldn't add public members, that security seems to have been removed.)
Also removes code which tries to detect "the unnamed List constructor",
which is no longer a thing, and a number of invocations of the constructor, where it's not clear that the test is aware that the constructor no longer exists, and is not marked as `@dart=2.x` with x < 12.

The `instanceof` operator needs a reference to the JavaScript class
instead of the Dart Type. This avoids an issue when changing the
type representation in the new runtime type system where the two
are no longer interchangeable.
Update the parameter name for `_jsInstanceof()` which which was
probably the remnants of a copy paste.

Change the calling convention of the sync* body to fix bugs and avoid allocations.
- Body takes the controlling _SyncStarIterator as a parameter.
- `yield` assigns directly to the `_current` field and returns.
- `yield*` calls a method on the controlling iterator (rather than returning the iterable). This avoids an allocation to wrap the iterable, a type test to distinguish `yield` from `yield*`, and allows the `get:iterator` call to happen in the dynamic scope of try-catch surrounding the `yield*` to that it will catch any exceptions.
- Avoid using IIFE to bind constants just to call the body.
- Use a dummy body to avoid the need to testing termination of the body.

An investigation of the two regressions shows that they benefit from a micro-benchmarking effect. The previous code was monomorphic at the property access in `receiver.constructor == Array`. If this is forced to be polymorphic, the baseline is quite a bit worse, leading to an improvement in line with some of the other benchmarks.

Also adds `firstOrNull`, `lastOrNull`, `singleOrNull`, and `elementAtOrNull`.
I chose `nonNulls` instead of `whereNotNull()`.
The latter should have been a getter, but isn't.
Making it a getter in the platform libraries would be confusing,
and make migrating from `package:collection`'s function harder,
so instead I gave it a completely new name.
The alternative would be to retain the non-idiomatic `whereNotNull()`
for familiarity. But then it would be tool late to fix.
