* Fixed an annoying number of undo bugs
* Original data for bmesh pbvh is no longer handled by the undo code.
This should eliminate a whole class of subtle and hard to track down
bugs.

Merge branch 'master' into geometry-nodes-curve-support

USD Export: texture export options.

Added Export Textures and Relative Texture Paths options.

Cleanup: rename IntegratorPathQueue for clarity

It's only counting the queue sizes, it's not the actual queue.

Cleanup: allocate active path arrays once in advance

In practice the size of this matches the max path states anyway, avoiding
reallocation in the middle of queueing kernels will simplify some things
later.

Cycles: add debug logging for CUDA device queue

Cycles: allocate Scene in Session, pass DeviceScene to path trace work

Needed for shader sorting.

Cycles: disable megakernel for now, see code comments

Cycles: add shader sorting for shade_surface kernel

* intersect_closest and intersect_subsurface compute a sorting key and with
atomics count how many paths are queued for each key.
* Then we compute the prefix sum of the sorting keys, and use that for sorting
paths according to the key in a single pass with atomics.

Cycles: Bring OptiX denoiser back

Basically putting old code to be used by the new denoiser
implementation in the integrator.

The main denoising function in the OptiXDevice was split,
to make it easier to follow and understand what's going on.

The current limitation is that currently it only works when
rendering on the OptiX device. Attempts to render on CPU and
denoise on OptiX will currently error out (error is printed
to the console, denoising is not run). This will be worked
on next.
