Schema to describe RtPrimvarList.
To obtain an RtPrimvarList we pass numUniform, numVertex, numVarying, numFaceVarying to the constructor, call RtPrimvarList::SetTimes if "P" (for points) is among the params and has samples and finally call the appropriate RtPrimvarList::SetFOO[Detail]( name, value[, detailType[, sampleTimeIndex]]).
The HdPrmanRileyPrimvarSchema determines what SetFOO[Detail] method is valled with what value, detailType or sampleTimeIndex.
For many data types or when detailType is constant, the behavior is the same as for the HdPrmanRileyParamSchema.
Otherweise, we call SetFooDetail using HdPrmanRileyParamSchema similar as we did for HdPrmanRileyParamSchema but consuming the detailType data source as well. The value data source is only sampled at time 0.
The "P" param is treated specially. It is the only param for which take time samples (from the sampled value data source) and always corresponds to a call to RtPrimvarList::SetPointDetail with detailType = vertex.

Builds a container data source which includes the provided child data sources. Parameters with nullptr values are excluded. This is a low-level interface. For cases in which it's desired to define the container with a sparse set of child fields, the Builder class is often more convenient and readable.
