In Flutter hot reload, the flutter_tools are calling the `getIsolate` to read the pause state of the isolate, which returns a full list of 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 for a large app. This change adds a new method to only read what is needed.
