In most cases, the (now removed) SDK class was patched so that the constructor redirected to a platform-specific implementation of the unmodifiable view. Uses of the SDK class in the platform code could be rewritten to the more direct use of the implementation class.
The big +/- file changes are from moving the implementation classes from the patch file (typed_data_patch.dart), where they are no longer needed, to the internal file (typed_data.dart).

This will enable the standalone embedder to resolve uris in a follow
up CL:
https://dart-review.googlesource.com/c/sdk/+/361881
The implementation was using zones for allocation, this CL switches
that to using `malloc`. The caller is responsible for freeing the

This CL removes `Dart_DefaultCanonicalizeUrl`.
We don't have a run_platform_tests, so this CL keeps the tests in

- Move DateTime implementation for dart2js and DDC into a shared place to reduce duplication.
- Add a _microsecond field to the web DateTime to track microseconds outside of the JavaScript Date.
- The cute dart2js optimization whereby `DateTime.now().millisecondsSinceEpoch` is compiled to `Date.now()` still works.
- Both implementations report better errors.

The existing implementation assumed, hardcoded, that the compilation
environment had an entry for any string of the form `dart.library.`+X,
with a value of either `"true"` or `""`.
This did not match the runtime behavior of the standalone VM,
which allows non-constant access to the compilation environment.
Changed to only have entries with value `"true"` for libraries
which exist.
This changes the value of `bool.hasEnvironment` or a
`String.fromEnvironment` or `bool.fromEnvironment` with a
non-default `defaultValue`.
The existing behavior was that `bool.hasEnvironment` was always true,
and that the other constructors ignored the `defaultValue`,
so most likely such tests or `defaultValues` aren't used anyway.

The patch files for these operators return a bool, whereas
the public API returns a JSBoolean. Since there's only one
possible return type, we should make them return bool for
convenience. Boolean conversion is also inexpensive on
dart2wasm, so that shouldn't be an issue.
Also adds helpers to operator_test to make sure any JS values
are converted before they're compared, adding additional type
checking through the conversion.

This change brings the CFE into alignment with the analyzer.

According to the patterns spec, the pattern context type schema for a
cast pattern should be `_`. What was actually implemented was
`Object?`.
This is unlikely to make a difference in practice, since (a) cast
patterns are unlikely to be used in circumstances where the pattern
context type schema makes a difference, and (b) it takes some effort
to come up with expressions whose type inference behavior is differenc
between a schema of `Object?` and a schema of `_`.

some refactoring to make ExportCreator a SharedInteropTransformer

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

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.
