Fix V86.destroy() with xterm.js (#720) 
`V86.destroy()` was throwing an error due to `SerialAdapterXtermJS`
having no `destroy()` method.

Wait for emulation to stop when destroying (#721) 
In some environments, the "emulator-stopped" event did not always fire
when calling the `destroy()` method. This waits for emulation to finish
stopping before continuing with the rest of the destructor.

When stopping the emulator with `.stop()`, the `v86` instance's state
would follow these transitions:

1. Before calling `.stop()`:
   ```js
   {
     running: true,
     stopped: false
   }
   ```
2. Immediately after calling `.stop()`:
   ```js
   {
     running: true,
     stopped: true
   }
   ```
3. After the emulator has finished stopping:
   ```js
   {
     running: false,
     stopped: false
   }
   ```

It was not immediately obvious how properties named `running` and
`stopped` could ever have the same values. This commit renames `stopped`
to `stopping` so it is slightly easier to understand while debugging.
