Vulkan: Batch Jackass' tiled in-place color grade

Jackass: The Game color grades the framebuffer in 32x64 tiles, one channel
per pass, texturing from the framebuffer it renders to. Each of the 225
draws became a depal pass plus a pass drawing it back, 450 render passes
per frame. A new queue hack, enabled by the TiledDepalHack compat flag,
sorts these pairs into waves of non-overlapping tiles and runs each wave
as one depal pass and one draw pass, leaving 6.

Output is byte-identical to before on both dumps from the issue, at 1x
and 3x on desktop, and at 1x on both phones below.

Time saved per post-processed frame, from replaying the dumps from the
issue with headless --bench (each replay renders that frame once):

  Redmi 9A (PowerVR GE8320):  ~145ms at 1x, ~180ms at 2x
  Unisoc UMS9632 (Mali-G57):  ~55ms at 1x and 2x

Either is more than a whole 33ms frame, so on those GPUs this pass alone
ruled out 30fps.
