Nvfp4 A16 Moe Plugin

class Nvfp4A16MoePlugin : public nvinfer1::IPluginV3, public nvinfer1::IPluginV3OneCore, public nvinfer1::IPluginV3OneBuild, public nvinfer1::IPluginV3OneRuntime

TensorRT V3 plugin for FP16/BF16 activations and Marlin-packed NVFP4 expert weights.

max_routed_rows is the capacity of the padded Marlin routing arrays, not only the number of selected slots. A runtime shape with T tokens requires at most T * top_k + num_experts * (block_size - 1) rows, where block_size is 8 for S == 1 and 32 otherwise.
