Closes https://github.com/dart-lang/sdk/issues/54138
Adds a helper to do better type-checks so that users don't
accidentally using is checks or have to manually do the right
typeof or instanceof checks. In order to do this, there is
some refactoring to make ExportCreator a SharedInteropTransformer
(as it's shared across all backends) so that we can reuse an
existing visitor. In the same class, we remove unnecessary setting
of parent pointers. We should clean up the fileOffsets as well,
but dart2js verifies that those are set, so we keep them as is
for now. Also adds some static errors for edge cases.

The current implementation externalizes and internalizes the Dart

This makes the implementation consistent with the JS backends.

In order to reach parity with js_util, we expose operators
through an extension and do some partial renames in order
to make the member names sound better e.g. `equals` instead
of `equal`. We also expose the following from js_util:
- NullRejectionException
We don't expose `isJavaScriptArray` and `isJavaScriptSimpleObject`
as they can expressed through other forms of interop. There
was an esoteric bug where we needed these members for Firefox
in pkg:test, but the package no longer uses these members, so to
avoid increasing the API space too much, we do not export them.
For the same reason, we also don't expose `objectGetPrototypeOf`,
`objectPrototype`, `objectKeys`.
We don't expose `allowInteropCaptureThis` as it will take some
work to handle this in dart2wasm. That work is tracked in
https://github.com/dart-lang/sdk/issues/54381.
Lastly, `instanceof` and `instanceOfString` is moved to be on
`JSAny?`, as this operator is useful to avoid needing to
downcast to `JSObject` e.g. `any.instanceOfString('Window')`
instead of `any.typeofEquals('object') &&
(any as JSObject).instanceOfString('Window')`.
Extensions are reorganized and renamed to handle these changes.

By using the `_addressOf` operator implemented in the VM, these fields

A quirk of analyzer and CFE implementations is that they resolve
property gets such as `foo.bar` to specific field or getter
declarations that may be not be directly defined on the target type;
for example if `foo` has type `B`, and `B` extends `A`, and `A`
contains a field called `bar`, then `foo.bar` is considered to refer
to `A.bar`, for example:
class A {
int? bar;
}
class B extends A {}
f(B foo) {
print(foo.bar); // Resolved to `A.bar`.
}
This is in contrast with the language specification, which makes a
clean distinction between class _declarations_ and the _interfaces_
implied by those declarations. While a class declaration can contain
(among other things) both getters and fields, which might be concrete
or abstract, an interface doesn't distinguish between getters and
fields, and is inherently abstract.
The advantage of the analyzer/CFE approach is that it allows more
intuitive error messages and "go to definition" behavior, which
benefits users. But it has some ill-defined corner cases involving
complex class hierarchies, because not every property access can be
resolved to a unique declaration (sometimes a getter is multiply
inherited from multiple interfaces, for example). The language spec
approach has the advantage of being well-defined and consistent even
in situations involving complex class hierarchies.
When I initially implemented field promotion, I took advantage of this
quirk of the analyzer and CFE implementations, so that I could make
property gets that refer to field declarations promotable, while
keeping property gets that refer to abstract getter declarations
non-promotable. This caused unpredictable behaviors in the ill-defined
corner cases. It also meant that in certain rare cases, a property
access might not be promoted even when it would be sound to do so
(e.g. a property access might refer to a private abstract getter
declaration, but the only concrete _implementation_ of that abstract
getter was a final field).
This CL changes the rule for promotability so that any get of a
private property is considered promotable, provided that the
containing library doesn't contain any concrete getters, non-final
fields, or external fields with the same name. It no longer matters
whether the private property refers to a field or a getter. This rule
is simpler than the old rule, restores the spec's clean distinction
between class declarations and interfaces, and allows more promotions
without sacrificing soundness.

The current `String.fromCharCodes` behavior, throwing if `start`
or `end` is larger than the length of the `charCodes` iterable,
is inconsistent with the argument being an `Iterable<int>`,
which the user is not expected to know the length of.
Most other operations that accepts or produces an `Iterable` and
restricts it to a range, will allow the range to exceed the length
of the iterable, acting like `.take(end).skip(start)`, just without
needing to create wrappers that hide the original value.
(`List.setRange` is another exception, and should probably be fixed
by allowing the range to be partially filled, since it's too hard
to change it to require a `List` argument.)
