Avoid AOP aspects to tweak core behavior

[bwaidelich]

Description

This is an umbrella issue that aims to reduce the amount of Aspect Oriented Programming in the core.

Background

Flow was created as framework for Neos. It seems weird that we have to adjust its behavior via AOP.
But more importantly: Those AOP aspects make debugging harder and weaken our API.

Examples

Some of the most important aspects to get rid of (IMO):

FusionCachingAspect

Caching aspect to speed up \Neos\Fusion\View\FusionView::getMergedFusionObjectTree().
We actually have two of those(!), one in Neos.Neos and one in Neos.Fusion itself.

Last bug: #3191

NodeTypeConfigurationEnrichmentAspect

Swiss army knife aspect that modifies the node type configuration adding i18n labels etc.
Wraps the \Neos\ContentRepository\Domain\Model\NodeType constructor

Partly resolved with #3087
Dedicated Issue: #2867

PluginUriAspect

Rewrites \Neos\Flow\Mvc\Routing\UriBuilder::uriFor() interpreting the internal __node argument.
I don't really understand what it does exactly tbh

SiteRepositoryCachingAspect

Caching aspect to speed up \Neos\Neos\Domain\Repository\SiteRepository::findFirstOnline() and \Neos\Neos\Domain\Repository\DomainRepository::findOneByActiveRequest()

If the cache is really needed (with the new routing it might not be so relevant) this logic should be moved into the corresponding repository (or into the consumer that relies on this to be fast)

NodeIdentityConverterAspect

Wraps \Neos\Flow\Persistence\AbstractPersistenceManager::convertObjectToIdentityArray() in order to make the nodes context path its technical identifier

-> #5069

RouteCacheAspect

Wraps \Neos\Flow\Mvc\Routing\RouterCachingService::extractUuids() and \Neos\Flow\Mvc\Routing\RouterCachingService::generateRouteTags() to tag route caches with the ids and workspace names of the involved nodes.

This should be done in the route part handler (see #3215 #3589)

AugmentationAspect (Neos.Ui) -> #3595

Wraps \Neos\Neos\Service\ContentElementWrappingService::wrapContentObject() adding neos-nodedata script tags.
This should be done via Fusion I suppose

FusionCachingAspect

is gone with #3839 ;)

The neos-nodedata script tags are now gone with neos/neos-ui#3770
