Make [TreatNullAs=NullString] DOMString arguments nullable instead

An IDL method declaration such as

  void f([TreatNullAs=NullString] DOMString x);

can be transformed into

  void f(DOMString? x);

without affecting behavior or generated code, so do that.

Arguments that also have [TreatUndefinedAs=NullString] can't be converted
this way (yet), so this CL leaves them unchanged for now.

MediaSource must use ref-counting to handle pending activity counting.

Switch MediaSource to deriving from RefCountedGarbageCollected, as
ActiveDOMObject::setPendingActivity() relies on ref-counting.
