Rationale:
Previous method cached graph information (instruction and call site
counts) on a per-function level, not accounting for potential
specializations. The improved method runs an extra constant folding
pass, and only caches per-function information for non-specialized
cases. As a result, we inling much better, see for example, the
added test as illustration.
Since we no longer cache for constants, compile-time may be increased
a bit due to the extra scan. In the long run we should consider
for common constant "situations" as the call site.

Eventually it should be handled by Procedure.isRedirectingFactoryConstructor, but that is
currently broken for patch files.
It appears the VM has no patches of that kind, but dart2js does.

For this to work properly, we first need the test infrastructure to have support

Closes#37153
Isolate.resolvePackageUri was the only API which had an implementation
across DDC and dart2js. The implementation in dart2js has been broken by
default since Dart 2.0.0 without a user implemented hook that is not
used on any public repo on github. Our current supported path for
invoking the compilers on projects disallows the import altogether on
the web and it is only usable with an older version of the
`build_web_compilers` package, or by invoking the compiler manually
outside of the build system. This CL does not break the ability to have
the import when invoking outside of the build system.
- Drop implementation for `Isolate.resolvePackageUri` from the dart2js
and DDC patch files.
- Drop all references to `defaultPackagesBase` since it is not used.
- Drop all tests under `isolate/browser` since we do not expect any
support on the web. Most of these tests would have already been
failing. Remove status file entries that refer to the deleted tests.

TransferableTypedData instances are one-use kind of thing: once receiver materializes it, it can't be used
again, once sender sends it out to an isolate, sender can't send it to different isolate.
Example of use:
sender isolate:
```
Future<TransferableTypedData> consolidateHttpClientResponseBytes(HttpClientResponse response) {
final completer = Completer<TransferableTypedData>();
final chunks = <Uint8List>[];
response.listen((List<int> chunk) {
chunks.add(chunk);
}, onDone: () {
completer.complete(TransferableTypedData.fromList(chunks));
});
return completer.future;
}
...
sendPort.send(await consolidateHttpClientResponseBytes(response));
```
receiver isolate:
```
RawReceivePort port = RawReceivePort((TransferableTypedData transferable) {
Uint8List content = transferable.materialize().asUint8List();
...
});
```

This is required because otherwise
Object() == null
requires the type signature of Object.operator==(Object o) to be
changed to Object.operator==(Object? o). Which I don't think is the
behavior we want.
Confirmation that this CL is correct has been sent to the language
team. I recommend we land, which will unblock my subtyping CL, and
roll back/readdress later if need be.

Mostly this is adding an abstraction so we can produce the jsonl files that will
allow us to track the status of each test individually.
On a separate CL I'll be moving the tests out of the current unit tests into
their own step in the test matrix.

Prior to this change, connection errors such as "Connection refused"
etc, are caught either by some error condition being detected by
the eventhandler thread and that error condition being propagated
to the Dart thread, or by the first read or write after a
"successful" connection failing with an error.
However, posix documentation for non-blocking sockets recommends
either checking getsockopt(SO_ERROR), or calling connect() a
second time following the first write event on a socket after
the first connect call returns EINPROGRESS.
On Fuchsia, this check is mandatory because errors like
"Connection refused" are neither signaled on the socket's
underlying OS handle, nor indicated by error returns from
read() and write().
This change adds the check, which is optional on other platforms,
but mandatory on Fuchsia, to the Dart socket connection loop
after the first write signal is asserted.

This adds support for BabelJS to test.py's dart2js compiler
configuration. When --babel is specified directly or through a named
configuration, test.py will run an additional step after dart2js that
post-processes the javascript output by running it through BabelJS with
the specified Babel configuration. BabelJS is added to the DEPS in its
standalone form. d8 is used to run BabelJS standalone to avoid adding
a dependency on NodeJS. d8 can only write to stdout but not to files or
stderr, which makes it necessary to change the test_runner to handle
commands that expect their output to be piped to a file.
Changes:
* Add --babel option to test.py.
* Add babel option to pkg/smith.
* Switch IE11 builder to use babel transformation.
* Fix option list comparison bugs in pkg/smith.
* Change dart2js compiler configuration to generate files using the
test name rather than just "out.js" (update test that relied on this).
* Remove runtime_configuration dependency on test_suite.
* Remove obsolete blocks adding --preview-dart-2 dart2js arguments.
* Make dart2js' compiler configuration more like DDC's.
* Remove createCommand method that is no longer used.
* Remove support for "OtherResources" which was only used for
dart:isolate tests on dart2js and DDC.
* Skip co19_2 tests that are slow to transform with babel.
* Simplify the timeout handling in the test runner with Future.timeout.

A negative result was wrongly returned as a positive value.
Since positive values are preferred, the implementation now adds the modulus
