28e1e33c32 radv: Don't use the depth image view for depth bias emission
If the application records a secondary command buffer that inherits
a render pass without specifying a framebuffer, we should still be able
to emit the depth bias state properly.

4303ea7b9a radv: Use a double jump to limit nops in DGC for dynamic sequence count.
Some RGP data showing that a large amount of NOPs might be a performance
concern.

Some data from a Granite demo repurposed as benchmark:
  - with max_count = 16, actual draw count 1-4, the new path is ~5% slower
  - with max_count = 2048, actual draw count 1-4, the new path is >2x as fast.
  - with max_count = 16384, actual draw count 1-4, the new path is >7x as fast.

Due to the new path being slower in e.g. small cmdbuffers I added a heuristic.
