When the number of draw calls is very large, instead of allocating
large amounts of batch buffer space for the draws, use a ring buffer
and process the draw calls by batches.

This will help for a follow up change where we will respawn the shader
multiple times in a loop and the base offset will be edited by the
shader itself.

The indirect draw count shader can be used as a more generic case of
the indirect draw one. We'll never enter the last condition of the
shader (writing the MI_BATCH_BUFFER_START) with non count variants of
draws.
