Danny Kabrane 4ce7b3d3ed MaterialX Pipeline: ...

- Add mapping of MaterialX pbr nodedefs to Material Functions
- Refactor MaterialX pipeline and MaterialXCustomize with a better handling of the different mappings (surface shaders, bsdf, etc.)
- Adding Material Functions placeholders for the mapping, no implemented logic in it yet, just here for the overload.
- Removing rest of unused code of MaterialX in the generic material pipeline
- Hiding MaterialSettings and Material Functions from MaterialX pipeline
- Overriding Material Functions only from Project Settings -> Engine -> Interchange MaterialX

MaterialX Translator:
- Adding support of pbr <surface> node
- Connecting outputs based on their index for multi outputs, used by node with material functions like <artistic_ior>
- Adapting the data structures for matching nodes and inputs, adding an optionalkey based on the nodegroup, particularly useful for <mix>, <add> and <multiply> nodes on BSDFs

MaterialX SurfaceShaders:
- Avoid a potential crash, by looking for an an approximate node definition during matching node and inputs resolution, since the the nodes are altered, for example nodes like blur.

MaterialX Pipeline Customization
- Making Enums in MaterialXPipelineCustomization only ReadOnly text instead of dropdowns

Substrate:
- Adding Substrate material functions counterpart of surface shaders and BSDF in the Substrate folder
- Adding support of Substrate for <surface_unlit>, <UsdPreviewSurface>
- Adding a CVar and a function in the InterchangeImportModule to check the availability of Substrate in the project settings and to enable or disable its support in Interchange.
