Creates an Observable notifying batches of DOM mutations happening anywhere in the
document (attributes, character data and child lists). Old values are not recorded, so
oldValue is always null.
The underlying MutationObserver is created lazily on first subscription and disconnected when
the last observer unsubscribes. It uses the Zone.js-free constructor returned by
getMutationObserverConstructor; subscribing throws if MutationObserver is not
available.
