Cleanup: make `struct PoseBackup` an opaque struct

Move `struct PoseBackup` into `pose_backup.c`, making it opaque to users
of the `ED_pose_backup_...()` functions. This produces a slightly nicer
API for the pose backup system.

Refactor Cycles X OIDN denoiser to use PassAccessor

No functional changes, just laying down code which is needed to denoise
passes different from combined.

Cycles X: Store information whether pass needs compositing on read

Currently unused, but will allow to properly feed pixels to the
denoiser (ignoring possible optimizations related on general scaling
rules).

Cycles X: Allow float3 access to shadow catcher pass

Cycles X: Initial implementation of shadow catcher denoising

Currently only implemented for OIDN denoiser.

Almost straightforward. The tricky part is the albedo pass: using the
real albedo causes unexpected discontinuity of the shadow catcher based
on the albedo of the surface the shadow is cast on. Worked around by
passing a fake albedo values. The downside is that it requires a full
frame of constant values. Not sure if there is a way around it.
