For isolates spawned by the application via `Isolate.spawn()`ed, the VM
will create a "lightweight" isolate and invoke the `initialize_isolate`
embedder callback to initialize it.
The embedder-provided callback will be invoked with the active isolate
and is expected to return with that active isolate - irrespective of
whether it succeeded to initialize or not.
=> The unsuccessful path was using `Dart_ExitIsolate()` - which is
incorrect.
This PR fixes that by not exiting the isolate. As a side-effect of the
fix, we also do less `Dart_EnterIsolate()`/`Dart_ExitIsolate()` calls in
initialization (which makes it faster) and handle failure to spawn the
root isolate. Furthermore this PR removes some dead code and replaces it
with `FML_DCHECK()`s instead.
The PR adds a test that will set the root library to null which will make the
engine fail initializing of the isolate and therefore trigger this error handling
path.

This PR changes how embedder API's SendKeyData sends ui.KeyData to the framework. The packets are now sent over the existing platform messenger, reusing the entirety of its code path and functionalities while keeping the embedder API unchanged
