Reviewed by Eric Carlson.

Instead of having a process wide value for DOMAudioSession type, store it in top level document.
This allows to clear it on navigation.

Add a m_state field in DOMAudioSession.
When its state is supposed to be changed, we now queue a task where we compute the new state and fire the statechange event if the new state is different from the old one.

Update RemoteAudioSessionProxy to send a configurationChanged event whenever the active state changes.
We do this since there might an ongoing configurationChanged message that may override the WebProcess remote audio session active state.
