Make VM always return empty array in the response.
Current implementation for this field comes with a bunch of complexity
because it locks message handler and then invokes Dart code which
makes it difficult to reason about various invariants. This code is
furthermore demonstrated to cause deadlocks. Given that nobody uses
it - it is simpler to remove this code altogether.

service/get_object_rpc_test was failing because one ID in it hadn't been
updated to the new format.
service/bad_reload_test was failing because `ServiceEvent::PrintJSON`
was attempting to populate the `reloadError` property of every `Event`
of kind `IsolateReload` with an `@Error`, but it was not possible to
allocate IDs for these `@Error`s because `ReloadSources` runs for an
isolate group, not for an individual isolate. I fixed this by removing
the `reloadError` property and adding a `reloadFailureReason` property

In Flutter hot reload, the flutter_tools are calling the `getIsolate`

libraries loaded in the isolate. The size of the return object grow
linearly to the number of Dart files, which can take ~500ms to transfer

This field was supposed[1] to replace Stack.asyncCausalFrames but IDEs
and other service protocol users never adopted it.
The mechanism for collecting awaiterFrames and asyncCausalFrames
was originally considerably different, but we have since unified
both[2] after we switched to lazy async stack traces[3].
Today the only differences between the two are:
- asyncCausalFrames represens async gaps explicitly, while
awaiterFrames does not;
- when asynchronous function is running its synchronous part
before the first suspension awaiterFrames will still represent
the corresponding frame as an asynchronous activation, while
asyncCausalFrames will treat the same frame as regular frame.
Consequently having this field does not add any value.
This CL removes it from the response and updates all tests to
test against asyncCausalFrames.

The java generation for type `(string|Null)[]` was creating `@return one of <code>List<String></code> or <code>ElementList<Null></code>`
see example:
```
@SuppressWarnings({"WeakerAccess", "unused"})
public class UriList extends Response {
public UriList(JsonObject json) {
super(json);
}
/**
* A list of URIs.
*
* @return one of <code>List<String></code> or <code>ElementList<Null></code>
*/
public Object getUris() {
final JsonObject elem = (JsonObject)json.get("uris");
if (elem == null) return null;
if (elem.get("type").getAsString().equals("String")) return new String(elem);
if (elem.get("type").getAsString().equals("Null")) return new Null(elem);
return null;
}
```
My change is the simplest thing I could think of, just making the return type `List<String>` instead and allowing some of the elements to be null. But I'm happy to implement something else if someone has a suggestion for a better type (along with how to get the generate code to produce it)
