BUG: Very slow doctrineDbalContentGraph projection replay

[dlubitz]

Currently the projection replay takes ages if you have a lot of events. This seems to be caused by the GraphProjectorCatchUpHookForCacheFlushing because of:

1. The catchUpHook get's called on each event and we can't disable that during replay -> AFAIK this will change anyway with @bwaidelich rework of the CatchUpHooks
2. ContentGraph::findParentNodeAggregates becomes slower on bigger datasets. Due to the mass on executions, this sums up very quickly. -> We might reduce the amount of call here with @mhsdesign PR for the ContentGraph::findAncestorNodeAggregateIds.

I also tried to optimize the ContentGraph::findParentNodeAggregates and may have found something. Not sure if I understand fully, but I think we can remove on join with hierarchyrelation, as we have all information we need in the first hierarchyrelation-join. Please check the PR #5268
