Cycles X: set integrator state size relative to the number of GPU cores

More specifically, 16x the max number of threads on all multiprocessors,
with 1048576 minimum.

What this effectively does is double the state size on the very high end
GPUs like RTX A6000 and RTX 3080 while leaving the size unchanged for
others. On the RTX A6000 I there are 2-10% render time reductions on our
benchmark scenes. The biggest reduction is on the barbershop interior, as
scenes with more objects and shaders are more likely to benefit from
improved coherence.

This also adds an environment variable for developers to test different
sizes, and debug logging about the size and memory usage.

Fix: incorrect force vector locations

While taking the weighted average of vector locations, the net normal
force was being used as the denominator. The correct value to use is
the sum of the magnitudes of all normal forces in the timestep.

Fix invalid address error in Cycles X GPUDisplay update

Make sure no display update happens after full buffer was written.
Makes it possible to free memory used by path trace works without
causing issues.

Viewport Compositor: Add DEG eval callback and redraw listener

This is pretty basic but it gets the job done. This may change in
the future.

The `NodeType` (SHADING) for the `OperationKey` is not ideal.

Also it seems the tagging comming from the nodetree tag everything
as COPY_ON_WRITE update. Which is slow. To investigate.
