Remove Static Component NetIds (#4247)

* Remove the unnecessary NetID property from ComponentState.

* Remove Component.NetworkSynchronizeExistence.

* Removed Component.NetID.

* Adds component netID automatic generation.

* Removed NetIdAttribute from serverside components with no corresponding clientside registration.

* Completely remove static NetIds.

* Renamed NetIDAttribute to NetworkedComponentAttribute.

* Add GenerateNetIds calls to client and server entry points.
Add test to make sure auto generated NetIds are identical.

* Component changes when rebasing that I am too lazy to rewrite into the branch.
