Remove `$node->subgraphIdentity->contentStreamId`

[mhsdesign]

Subtask of https://github.com/neos/neos-development-collection/issues/4564

The contentStreamId is currently still used

• [x] in Neos.Seo -> https://github.com/neos/neos-seo/pull/187
• [x] in the Node
• [x] in the NodeAggregate
  • [x] all usages removed
• [x] as cache identifier for subgraphs (in its identity)
• [x] in property adjustments for publishing events based from a node
• [x] in the e2e test in the NodeDiscriminator::fromNode -> https://github.com/neos/neos-development-collection/pull/5169
• [x] in the NodeCacheEntryIdentifier and Neos.Caching.entryIdentifierForNode -> https://github.com/neos/neos-development-collection/pull/5083
• [x] in the old legacy NodeAddressFactory -> https://github.com/neos/neos-development-collection/pull/5068
• [x] in the Fusion CacheTag -> https://github.com/neos/neos-development-collection/issues/4810
• [x] for equals check against AssetUsageReference (because the asset usage stuff is not workspace aware yet)
  • [x] will be fixed via https://github.com/neos/neos-development-collection/issues/5084 , but as the used part is currently broken either way we can go ahead: https://github.com/neos/neos-development-collection/issues/5145

as @dlubitz wrote

AssetUsageProjection needs to hold the workspaceName, so we don't need to fetch workspaceName by contentStreamId anymore (See)
