async_hooks: remove experimental onPropagate option

The `onPropagate` option for `AsyncLocalStorage` is problematic for a
couple of reasons:

1. It is not expected to be forwards compatible in any way with the
   upcoming TC-39 `AsyncContext` proposal.
2. It introduces a non-trivial O(n) cost invoking a JavaScript callback
   for *every* AsyncResource that is created, including every Promise.

While it is still experimental, I recommend removing it while we can
revisit the fundamental use cases in light of the coming `AsyncContext`
proposal.

-> Stability: 1 - `options.onPropagate` is experimental.
-
-* `options` {Object}
-  * `onPropagate` {Function} Optional callback invoked before a store is
-    propagated to a new async resource. Returning `true` allows propagation,
-    returning `false` avoids it. Default is to propagate always.
-
 Creates a new instance of `AsyncLocalStorage`. Store is only provided within a
 `run()` call or after an `enterWith()` call.
 
-The `onPropagate` is called during creation of an async resource. Throwing at
-this time will print the stack trace and exit. See
-[`async_hooks` Error handling][] for details.
-
-Creating an async resource within the `onPropagate` callback will result in
-a recursive call to `onPropagate`.
