Change how the workbench is synchronized and remove the shared `Inventory.Type`

[IntegratedQuantum]

After #2506 there are only two shared types: .workbench and .normal
The workbench should be reworked to be more client-centric:
The server-shared inventory should only have 25 slots, the output slot should be client-only
To synchronize crafting a new inventory command should be added, as was done in #2506 for inventory crafting.
This will reduce the number of edge cases to check for in the networking code.
