TASK: Remove legacy NodeAddress and NodeAddressFactory

[mhsdesign]

Neos Ui adjustments neos/neos-ui#3858
Fixes final parts of #4564

As bitterly debated in #5072 we will change the serialisation format of the CR Node in URLS and in the Neos UI.

Currently there is a big legacy corruption layer around the WorkspaceModule, NeosUi and the Nodes controller using the ancient Legacy NodeAddress and NodeAddressFactory to work with the legacy format. This is part of the migration strategy and will be cleaned up in this change.

For reference the Neos Ui's content node serialisation:

- Neos 8.3
onedimension.localhost:8081/neos/content?node=/sites/neos-test-site@user-admin;language=en_US

- Neos 9.0-dev (currently)
onedimension.localhost:8081/neos/content?node=user-admin__eyJsYW5ndWFnZSI6ImVuX1VTIn0=__f676459d-ca77-44bc-aeea-44114814c279

- Neos 9.0 next beta, this pr
onedimension.localhost:8081/neos/content?node={"contentRepositoryId":"onedimension","workspaceName":"user-admin","dimensionSpacePoint":{"language":"en_US"},"aggregateId":"000b42ff-c9d3-4b5e-b6de-56d35832dc0e"}
