async_hooks: add an InactiveAsyncContextFrame class

This gives a class prototype for AsyncContextFrame that contains the
required methods, so that when we swap the prototype,
ActiveAsyncContextFrame methods are used instead. Previously, the
methods were defined in AsyncContextFrame, so swapping the prototype
didn't swap those static methods.

Also, make the ActiveAsyncContextFrame extend from Map.
