DynamicPropsManager
Takes care of dynamic Props
Usage from DynamicPropsExtension
Unique per DynamicPropsExtension instance, which calls onBindComponentToContent and {#link onUnbindComponent} when it binds and unbinds Components respectively.
When Component is being bound, a DynamicPropsManager subscribes to DynamicValues that its represent dynamic props, and keeps the mounted content the Components is rendered into in sync with get until the Component gets unbound, at which point, the DynamicPropsManager unsubscribes from the DynamicValues.
