WIP: HLSL: structuredbuffer counter functionality
This is WIP, heavy on the IP part. There's not yet enough to use in real workloads. Currently present: * Creation of separate counter buffers for structured buffer types needing them. * IncrementCounter / DecrementCounter methods * Postprocess to remove unused counter buffers from linkage * Associated counter buffers are given @count suffix (invalid as a user identifier) Not yet present: * reflection queries to obtain bindings for counter buffers * Append/Consume buffers * Ability to use SB references passed as fn parameters
