rr: Cyberpunk's extra inputs (SSS guide, colour before particles) and hardware depth

- GameFrameR/RFrameImages: DLSSD.ScreenSpaceSubsurfaceScatteringGuide (arg 264)
  and DLSSD.ColorBeforeParticles (output stage, texture 416 with its own history
  pair 384/392, zero-initialised on first use); guides array 6 -> 8
- DLSS.Use.HW.Depth: byte 980 and output byte 443 bit 24 (Cyberpunk passes the
  nonlinear depth buffer); replay's 'inverted' field becomes a bitmask
- shim: bind the two new resources, read the HW-depth flag, and accept every
  preset hint except E's 5 by mapping it to D's diamond_wallaby kernels
  (harness captures show 0x80000002/0x80000005 run preset D)
- harness: D4R_HARNESS_RR_EXTRA=particles,sss and D4R_HARNESS_RR_HW_DEPTH=1
- ptx2rr: out-of-range integer fetches return zero, matching ZLUDA's behaviour
  (the reference the stages are checked against)
- engine/rr/README: the capture findings behind the offsets
