ID 366282 - Graph State sent to `RendererInfoBase::fillRenderTerminalOps()` doesn't include accurate multisample/shutter attributes

Problem summary:

graphState included as part of the stateArgs argument doesn't appear to include shutter/numSamples values computed as part of the useMaxTimeSamples-style double-cook that happens when renders are triggered.

As a result, render terminal ops which want to make use of system args (directly or indirectly via Foundry::Katana::GetNumSamples) will not get accurate values.

Workaround:

read the attrs directly from /root -- but it's generally cleaner to rely on the "system" args as they can possibly differ.

Tested versions/platforms:

On a small dev investigation this appears to be a bug that predates the 2.X line
