Copy counter value of append/consume buffer into another buffer.
Append/consume and counter buffers (see ComputeBufferType.Append, ComputeBufferType.Counter) keep track of the number of elements in them with a special counter variable. CopyCount takes a buffer as
src, and copies its counter
dst buffer at given byte offset.
This is most commonly used in conjunction with Graphics.DrawProceduralIndirect, to render arbitrary number of primitives without reading their count back to the CPU.
On DX11 there is a restriction on the
dst buffer - it must have been created with ComputeBufferType.Raw or ComputeBufferType.IndirectArguments type. On other platforms
dst can be any type.
