Binyang Li 8896cd909a Add ROCm FP8 E4M3B15 support (#774) ...

## Summary

Add ROCm (gfx942) support for the FP8 E4M3B15 data type, including
optimized conversion routines between FP8 E4M3B15 and FP16/FP32 using
inline assembly.

Extends the allpair packet and fullmesh allreduce kernels to support
higher-precision accumulation (e.g., FP16/FP32) when reducing FP8 data,
improving numerical accuracy.

Adds Python tests to verify that higher-precision accumulation is at
least as accurate as native FP8 accumulation across all algorithm
variants.
