- Previously exec inputs/outputs were stored along with other (data) inputs/outpus
- Problem is, for exec pins, we want each output to only support 1 connection, but multiple connections to each input. This is the opposite of data, where we support multiple output connections, but only 1 input connection
- So we flip the representation around, and store output pointers, rather than input pointers...this also better matches the way we iterate exec connections while compiling
- This does complicate some UI logic, as now input/output graph pins no longer line up exeactly with UMaterialExpression inputs/outputs (we still have a flat list of pins, but separate lists of exec/non-exec inputs/outputs)

- Very WIP, not intended/ready for production use
- Hidden behind CVAR to enable support, and per-material flag to opt in

Strata material compiler general improvements.
- Created a headers shared between code and shaders
- Build up an internal representation of the material layer (BSDF horizontal mixing per layer)
- Output more meaningful errors for the user to understand what is wrong if using too many BSDFs or layers, etc. (exemple Adding would result in too many BSDFs in a Layer) Important if artist start to use what we currently have to not have them whaste time.
- Add a debug as text in the hlsl code showing the material setup as well as in the material compilation stats.
This later will open other possibility: shared normal cache between layers or per material max byte count instead of max BSDF count.

Add composite & pinbase expressions / nodes, which use reroutes under the hood to ensure zero material overhead.
Convert MaterialEditor to a WorkflowCentricApplication.
Generally add subgraph existence support to MaterialGraph / MaterialEditor.
