turnip: Only emit descriptor loads for active stages in the pipeline.

zink has a push descriptor template layout that has every possible stage,
which gets used regardless of what stages are in the pipeline.  By
skipping over the unused stages, we cut the CP overhead.

Improves TU_DEBUG=sysmem gfxbench gl_driver2 on zink by 6.57% +/-
0.331143% (n=5).
