Call all destroy hooks. This should only ever be called once. An error will
-be thrown if it is called more than once. This must be manually called. If
-the resource is left to be collected by the GC then the destroy hooks will
-never be called.
runInAsyncScope<This, Result>(fn, thisArg?, ...args): Result
Call the provided function with the provided arguments in the execution context
-of the async resource. This will establish the context, trigger the AsyncHooks
-before callbacks, call the function, trigger the AsyncHooks after callbacks, and
-then restore the original execution context.
