Description

Currently, we only support float16 and float8 tensor core on B200 (the tcgen05 instruction set). We need to support nvfp4 tensor core for the self.tcgen05.mma instruction, and add a kernel example.

Research direction

Locate the existing B200 support for float16 and float8 in the self.tcgen05.mma implementation, then review how its kernel examples are structured. Add nvfp4 support for that instruction and a corresponding kernel example; done means the new example demonstrates the supported path.
