Append-consume ComputeBuffer type.
Allows a buffer to be treated like a stack in compute shaders. Maps to AppendStructuredBuffer<T> or ConsumeStructuredBuffer<T> in HLSL.
The stride passed when constructing the buffer must match structure size, be a multiple of 4 and less than 2048.
See Microsoft's HLSL documentation on AppendStructuredBuffer and ConsumeStructuredBuffer.
The buffer size value can be copied into another buffer using ComputeBuffer.CopyCount, or explicitly reset with ComputeBuffer.SetCounterValue.
