Fix various CUDA rendering issues with new integrator

* Mark paths outside of the total work size as terminated
* Error in device_vector.copy_from_device implementation
* Don't assume sort_intersections works for 0 hits
* Remove feature flags from integrator state, this is to be handled
with SoA selective array allocation instead.

Fix T84988: Armature symmetries crashes with action constraint

Action constraint without an action pointer set was crashing.

Fix T79999: Double color management applied during viewport animation render

In 2.81 there was a change to increase the performance of viewport
animation rendering. This change would perform the color management on the
GPU if the only 8bit was needed. This saved CPU cycles and data
transfer.

The issue is that in the image editor or when saving the image the CM
will be reapplied. Although the speed is desired, exporting the actual
colors has more priority.

In the ticket there is an analysis that shows that shows that this fix
is the correct short term step to take. It would be better that the
render result is aware of the color space of its buffers so the applying
color management could be skipped when saving to disk or drawing in the
image editor.

The issue with this change is the performance penalty it has.
