refactor: update workgroup size in compute shader and dispatch logic

Modified the workgroup size in the state-update compute shader from 1 to 64 for improved parallel processing. Adjusted the dispatch logic in StateUpdatePass to calculate the correct number of workgroups based on the new size, enhancing performance during state updates. Removed unnecessary terrain parameter upload in TerritoryRenderer to streamline resource management.
