async_hooks: add an InactiveAsyncContextFrame class

[bengl]

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.
