Add support for the UsdPrimvarReader_TYPE templates for both import and export. These are used by several USD test assets and support here represents the last major piece of the UsdPreviewSurface spec to be implemented. On import these become `Attribute` nodes and on export the `Attribute` nodes will become `UsdPrimvarReader_TYPE`'s accordingly. Import: - `UsdPrimvarReader_float` and `UsdPrimvarReader_int` will use the `Fac` output - `UsdPrimvarReader_float3` and `UsdPrimvarReader_float4` will use the `Color` output - `UsdPrimvarReader_vector`, `UsdPrimvarReader_normal`, and `UsdPrimvarReader_point` will use the `Vector` output Export (only `Geometry` Attribute types are considered): - `Fac` will use `UsdPrimvarReader_float` - `Color` will use `UsdPrimvarReader_float3` - `Vector` will use `UsdPrimvarReader_vector` - `Alpha` is not considered MaterialX note: Hydra-native support is a bit more involved and will have to be done separately. Hydra w/USD sync is trivial to implement but those changes have been left out here. Pull Request: https://projects.blender.org/blender/blender/pulls/135143
