The issue here is that for draw indirect count variants, we want to
jump after the last generated draw call to the next location where
commands are. But if we have more than 67M draws (8k * 8k chunks), we
only know the location once we've generated each of the 8k * 8k
chunks.
This change adds a CPU side pointer in the push constant struct so
that we can create a single linked list of chunks to edit and go
through to write the correct jump address after all the generated
space has been allocated.
