[perf] review markCreated, markForDeletion, finalizeForDeletion algorithm

Whe using PPS, ComponentTagHandlerDelegate.apply:

1) generates a unique id: String id = ctx.generateUniqueId(_delegate.getTagId());
2) stores it in component.attributes under key MARK_CREATED c.getAttributes().put(ComponentSupport.MARK_CREATED, id)

both steps creates new instances (StringBuilder, HashMap.Entry).

But is seems, that this MARK_CREATED is used only in case of RefreshingTransientBuild = true and it is probably not necessary create and store that id for every component.
