When growing an array, we're checking if element type is nullable.
The problem is that 'null is! T' is true for legacy types T
(other than top types and Null), so it throws for List<int*>.
In order to be able to grow arrays with all element types which can
hold null (including legacy element types) this test is changed to
null as T;
which throws type error if T cannot hold null.

The constructor was wrapping the onData handler to hide the type-mismatch. This
copies the same logic to the onData handler.
In non-nnbd code this code was not exercised. The migration of dart:async
made this code reachable on our tests. That's because Stream.first used to
do:
var subscription;
this.listen(() => ... cancel subscription here, ...)
it now avoids making subscription nullable by registering the onData handler
later:
var subscrition = stream.listen(null, ...);
subscription.onData(() => ... cancel subscription here);

The least upper bound of _SyncBroadcastStreamController and
_SyncStreamController is StreamController (according to the CFE) leading
to an implicit downcast from StreamController to _StreamControllerBase.
The analyzer and CFE sometimes disagree on the hierarchy depth
computation (see https://github.com/dart-lang/sdk/issues/38377)
which is probably the root cause of this.

Work towards https://github.com/flutter/flutter/issues/46724
Background:
on the latest versions of iOS today, we have to use mdns to discover the observatory port and authentication code. For a variety of reasons this can fail, leaving us with no way to connect.
An alternative approach is to specify the observatory port and disable the authentication code. If binding to this port fails, however, we would still like to attempt connecting with mdns.
Overview:
This adds a new flag to the dart SDK, --enable-service-port-fallback. This amends the behavior of the vmservice with a specified port. After failing to bind 3 times to a non-zero port, update the port selection to 0.
Results:
Tested locally two dart VMs with the same specified port:
```
