Cycles X: Remove dead resumable render code

It will be implemented differently by specifying an EXR file.

Remove the command line arguments to avoid false perception
that the resumable render still works.

WIP: Cycles X: Schedule work based on occupancy

Sacrifice refresh interval and increase GPU occupancy, lowering the
final render time.

Lowers `Blender 2.80 - Spring` demo file form predicted 30min
measured 3 min to render 1/10th of samples) to about 7.5min.

It is still considerably higher than the master branch, which finishes
the file in just below 3 min, but it is already a better results.

The timing is from RTX 5000.

The viewport and CPU rendering should stay unaffected by this change.

Cycles X: Re-implement tile highlight

Since the GPUDisplay usage for offline rendering we've lost tile
highlight functionality. This change brings it back.

Introduced new RenderEngine API call to manipulate highlight state
without acquiring RenderResult (so that we don't allocate passes).

Not fully ideal since the last tile will be highlighted after render
is done until first full-frame is done, but is a cosmetic thing we
can improve in the future.

Cycles X: make progressive multi-jitter the default sampling pattern

Now that adaptive sampling is enabled by default this was already the case in
practice, but use it now also for the non-adaptive case so the sampling patterns
stays consistent when switching that on and off.

A reason to do this now is that we will need to update all the test reference
images for the cycles-x merge, and those are all affected by the sampling pattern.

Cycles X: Improve performance of transparent shadows with OptiX

This changes the shadow record-all any-hit program to accept all
hits (return without calling `optixIgnoreIntersection`) beyond
the furthest distance recorded after the maximum number of hits
that can be recorded was reached.
OptiX will not call the any-hit program anymore for hits beyond
the distance of the accepted hits and also reduces the current
ray length behind the scenes. As a result performance improves
drastically in scenes where shadow rays can hit a lot of
transparent objects, like the "koro" benchmark scene.

With this applied I now get similar performance with both CUDA
and OptiX in "koro". Not quite perfect yet, but much better than

Cycles X: Real memory saving when using tiled rendering

The general idea is to delay reading EXR files for until after all
view layers are rendered. Once they are all rendered, BlenderSession
frees up as much memory as possible, and initiates processing of the
on-disk files.

The processing includes reading the file, optional denoising of the
full frame (if the denoising is enabled), and writing the result via
the write callback.

The processing is done as a state-machine which routes specific calls
to a full-frame processing, which allows to re-use same tile write
callback in the software integration.

In order to be able to know which view layer and render view is being
written the API has been extended to write layer and view names. Done
via BufferParams, as layer and view concepts are quite typical for the
EXR files.

The BufferParams also contains all fields needed for buffers access
outside of the scene graph.
