[0035] Support Wave and Thread Group Scope functions in Node Shaders

[anupamachandra]

Which document does this relate to?
[0035]- linalg::Matrix

Describe the issue you see with the spec
https://github.com/microsoft/hlsl-specs/blob/main/proposals/0035-linalg-matrix.md#stage-availability
The current spec allows Thread Scope functions in all shader stages but Wave and Thread Group scope only in compute shaders. We would like this to be extended to node shaders : Broadcast and Coalescing launch modes. Broadcast and Coalescing node shaders are basically compute shaders and enabling the full LinAlg functionality in these will allow interesting opportunities to combine neural shading and workgraphs.
