Valentin Shergin b1814b37aa Fabric: Lock-free events 2/n: Reimagining of EventTarget
Summary:
EventTargetWrapper and EventTarget were merged into one class that controls an `instanceHandle` reference and extracting a strong reference to it.

This diff also decouples the operation of retaining a strong reference (with checking a `enabled` flag) from actual usage of this reference. This allows to wrap into a mutex only first part of this process and avoid possible deadlocks.
