This is a very simple change that adds emission to the other material params that are exported as per the UsdPreviewSurface spec (see https://graphics.pixar.com/usd/release/spec_usdpreviewsurface.html). This has the same issue as some other exporters in that it's not clear whether it should be mulitiplied with 'Emission Strength' first. Regardless, this works for my needs.

I think it should be multiplied with emission strength. If either emission strength or color is linked to something I guess there is no better solution? But when both are constants it can be done.

Similar to #104506 (comment), I'm testing out the universal-scene-description branch.

@expenses I'm sorry overlapping work was done inadvertently. Thank you for starting the review process and discussion for this issue in this PR. Thanks also for raising the question of how to handle the emission multiplier. This is definitely a good topic for further discussion, as we don't have a good solution for this yet.

I am closing this PR for now, but please feel free to reopen it or create a new one if there are additional issues you'd like to address.
